Yes, you can use the same license key on your new computer but be sure to remove the product from the old computer when you are finished. 

You will need the number of licenses to match the number you have for terminal server. 

In this case, you will need two.  You will need one license per computer. 

Latest English version: 14.50.0010; Latest Japanese version: 14.20.0019; Latest desktop command line version: 14.40.0028

Yes, both 32-bit and 64-bit versions of the the Policy Manager program are available from PKWARE. If you are already using PKZIP / SecureZIP Enterprise or the Policy Manager on a 64-bit machine, you can download the new 64-bit Policy Manger installer from the Desktop Products update page. If you do not yet have PKZIP / SecureZIP Enterprise, the 64-bit software dowload now includes the 64-bit Policy Manager installer.

Customers running PKZIP or SecureZIP for Windows Desktop on Microsoft Windows 8.1 should use version 14.20.0019 or newer. Customers using earlier versions of PKZIP / SecureZIP on Windows 8.1 may experience a loss of functionality for operations using Drag-and-Drop. This includes operations such as dropping files onto the Desktop icon, or creating ZIP files using Explorer context menu.

Yes, versions of PKZIP / SecureZIP  14.40.0028 and later are supported on Windows 10.  Some customers may experience load delays, or unloading of the PKWARE Outlook plug-in due to reduced load times from Microsoft.  Customers can contact PKWARE support for information on re-enabling this plug-in.

Yes, there are currently no known issues using the CLI program under Windows 8.0 or Windows 8.1.

No, PKZIP / SecureZIP Command Line (CLI) is designed to only run on Windows Desktop operating systems (Win7, Win8, Win10) and will not run on a Windows Server operating system. If you need a command line interface for a Windows Server operating system, try out PKZIP / SecureZIP for Server which is designed for server needs.

Some customers running PKZIP or SecureZIP for Windows Desktop on Microsoft Windows 8.1 have reported they can no longer use Windows keyboard shortcuts such as Ctrl-A to select all files. While this capability is not controlled by PKZIP / SecureZIP we currently are investigating this issue to identify if there is anything that can be changed in PKZIP / SecureZIP to resolve this.

During an upgrade or uninstall of PKZIP / SecureZIP, a prompt may appear if the Windows Explorer requires a restart to complete the uninstall / upgrade. This restart may be required to add or remove PKZIP / SecureZIP actions from the right-click context menu. Windows may fail to restart Explorer preventing program and file access. To avoid this issue when upgrading or uninstalling PKZIP / SecureZIP, should this prompt appear asking you whether Windows Explorer should automatically be closed, choose "Do not close applications". When the update / uninstall is complete, reboot your computer. If you already chose to auto-close Explorer and have run into this situation, press ctrl-alt-del. You have two options:Restart your computer (display the shutdown icon)If you have other programs running, you may prefer to start the Task Manager. Stop this instance of Explorer; Windows will restart it.

To ensure integrity of the application software, PKWARE digitally signs .EXE and Enterprise PKSFX installation files. Depending on the version of the software you are installing, the digital certificate may have expired. Don't worry, the signature on these files remains valid and the software remains fully operational. This message just reports that the certificate used to sign the software when it was first released is now expired and will no longer be used for new digital signatures. This only occurs if you are installing an older version of the software that was signed during the valid signing period for the certificate. We would recommend checking our Product Updates page for newer versions to ensure you have access to the latest programs and features. You can continue to install and use the software if the installation reports the "Certificate is expired" warning. To continue with the installation, just press Okay to continue.

This problem is likely due to a documented problem with the GPG4WIN software that most likely was used to create the encrypted file. We recommend asking the sender of this file to either obtain a newer version of the GPG4WIN software, or to use SecureZIP instead.

Having taken our best efforts to continue supporting our products on this platform we have determined that support for Windows XP is no longer possible. Version 14.4 and later from PKWARE are no longer supported on Windows XP.

Microsoft has announced the end of extended support for Office 2003 will take effect on April 8, 2014. At that time, PKWARE will not discontinue support for this Office version. However, our ability to provide continued support for this platform may be significantly reduced with no further support available from Microsoft. We will take our best efforts to continue supporting our products on this platform for the foreseeable future, but the availability of continued Quality Assurance testing, fixes and product enhancements may be limited.

With the V14.2 release support for the older style conventional Windows interface has been discontinued. The Fluent (or Ribbon-style) interface is now the only UI supported for the Windows Desktop. With this change, the menu option to change between interface styles is no longer provided.

PKZIP / SecureZIP V14 is supported on Windows 7 through Windows 10.

We have fully tested SecureZIP and PKZIP v11 and 12.x on Windows Vista and v12.4 and later on Windows 7. and both programs are fully compatible and supported.When installing or using earlier versions of PKZIP / SecureZIP on Vista or Windows 7, be aware of the following known limitations:You may need to log in as Administrator to install the application.File associations for ZIP and other file types may need to be set as an administrative user.You may need to resize the column widths for certificate lists displayed on the passphrase / recipient selection dialog.Dialogs may not display full graphics capabilities under Windows Aero.You will be unable to use the diskette format and wiping feature of PKZIP / SecureZIP.

Yes. PKWARE products are tightly integrated with Microsoft Office to provide compression and encryption of email messages and attachments. PKWARE products are typically able to auto-detect Microsoft Outlook to install the appropriate options.

You likely have a document or spreadsheet created with Office 2007 or later. These Office files have the .docx or .xslx extension, and are zipped XML files. SecureZIP will attempt to "unzip" the file, and generate the error. Right click on the file and choose Open With to open the file in the appropriate Office application.

You likely have a document or spreadsheet created with Office 2007. You will need to reinstall the Office 2007 Compatibility Pack. See http: / / support.microsoft.com / kb / 924074 for more information.

You will see this message from a number of applications you may run if you have not configured third party application DLL's as trusted. This dialog is automatically displayed by Outlook in order to better protect systems from the spread of e-mail-bourne viruses. Microsoft has implemented this protection to prevent unauthorized access to your address book. This dialog may appear on systems running Outlook 2003, Outlook 2002 and Outlook 2000 with SP2. It is reported most commonly on Outlook 2002 / XP with SP3. It can also appear on versions of Outlook earlier than 2000 and on Windows 98 if you have installed the Outlook E-mail Security Update.When this dialog appears, it is to inform you that an application program is trying to access your address book. You must confirm this access is allowed in order for the application to proceed. You can configure your system to trust applications you use frequently to avoid repeatedly seeing this dialog for those applications authorized to run on your machine.This dialog may appear when using SecureZIP within Outlook to encrypt and send message attachments if you have not configured SecureZIP as a trusted application. To establish SecureZIP as a trusted application, you must configure the PKWARE Outlook integration DLL PKOutAdd.DLL within your Outlook Security Settings folder.Microsoft provides detailed instructions for establishing the Outlook Security Settings folder. Please reference the Microsoft Knowledge Base article OL2000: Administrator Information About the Outlook E-mail Security Update ( http: / / support.microsoft.com / ?kbid=263297 ) for information on administering your Outlook security settings.

This indicates the PKWARE Software Publisher Certificate used to sign the installation package has expired. To ensure the integrity of all software delivered to customers, PKWARE digitally signs all installers to provide assurance that they come from PKWARE and can be trusted. This message indicates the certificate use by PKWARE has expired. This expiration means that PKWAREs current certificate will no longer be used to sign new software packages we provide in the future. It does not mean there is any problem with the installer you received, and the signature it contains remains valid. PKWARE is already using a new certificate for new installers. Please note - this notice does not prevent the software from installing, and DOES NOT impact the operation of the software. Affected installers of our current products for v12.51 have been updated to use PKWAREs current certificate.To view a detailed explanation of this issue, click here .

PKZIP / SecureZIP startup time may be affected by attributes within your digital certificate. If you received your certificate from a CA that includes settings for Authority Information Access, your system may be checking online with your CA for information of certificate status, or for confirmation of the CA's signing certificate. These checks may take time and can be even more adversely affected if your network environment prohibits such checks. Determine if your online access is allowed. If your certificate includes an Access Method of On-line Certificate Status Protocol, you can disable CRL checking within your SecureZIP options. This will instruct SecureZIP to specify not to check online. If your certificate includes an Access Method of Certification Authority Issuer, then try installing the CA signing certificate(s) into your local certificate store.

No, You can install and use the Policy Manager on a system that is not running SecureZIP / PKZIP and if you are not the Policy Administrator you most likely do not want them on the same machine. SecureZIP only needs access to the Policy file (.szp) and the registry entries created using policy.

If you have installed the Policy Manager onto a machine that is not running SecureZIP, the PKSFX option will not appear unless this machine has a copy of the PKSFX.DAT file that is installed only with SecureZIP. To manage PKSFX options using policy you will need to copy this file to your machine running the Policy Manager.

The default operation of PKZIP / SecureZIP for Windows Desktop is to check for new versions weekly. Whether to check or not is determined each time a program component starts up. This can occur when the standalone UI starts, or when integrated components such as PKTray, Explorer, or Outlook start. If you find this does not occur, first check if you have the Check for Updates option enabled in the General settings under Miscellaneous options. This option may be disabled by policy on your system. Versions 12.0 and later may fail to enable this check even if configured in options. To resolve this condition, open the General tab under Miscellaneous options, change any setting and save the options settings. If the option you changed is not one you want preserved, set it back to it's prior setting and save the options again. If enabled, this check should now occur at the configured frequency.

ZIP is the most interoperable compressed file format in the industry. This format is used in countless applications and is copied by countless ZIP compatible programs. The specification for ZIP files is published so all developers can create compatible ZIP files. Compatibility is important to ensure your files can be opened by anyone you send them too. Unfortunately, many developers that claim to be ZIP-compatible often fail to implement support for all of the features supported by this format. 7zip and others, have failed to provide full interoperability for ZIP files and many features of ZIP such as some compression and security methods as well as split ZIP archive support are not provided. PKZIP / SecureZIP by PKWARE supports all capabilities to ensure full interoperability of zipped data.

No. PKARC is a program originally developed by PKWARE. This software has not been developed or supported for over 20 years.; There have been links available on the internet that still pointed to some old versions of this software and we understand some archiving programs may still support this format. We are not aware of any programs that include this capability that will run on 64-bit Windows. Some additional information on this format can be found at http: / / fileformats.archiveteam.org / wiki / ARC_%28compression_format%29. You may also want to look into 16-bit emulators that may allow you to run 16-bit applications under 64 bit Windows. One option we have heard of is called DOSbox which allows users to run vintage computer games from the same era as PKARC.

PKWARE has identified a compatibility issue that may affect customers using SecureZIP v8.0 and newer that have also installed a Microsoft Security Patch for Outlook 2003 (KB2293428).Customers installing a Microsoft security patch for an Outlook 2003 issue that is described in Microsoft Security Bulletin MS10-064 may experience problems automatically sending encrypted messages using SecureZIPs Outlook integration feature. Further, some customers may experience messages sent without encryption.Microsoft has documented information about this Outlook 2003 security issue in the Knowledge Base article found here: http: / / support.microsoft.com / kb / 2293428 . A problem has been acknowledged by Microsoft with this patch and has indicated it affects multiple vendors, including PKWARE. Specific information on the problem resulting from installing the KB2293428 patch is outlined in a subsequent Knowledge Base article referenced as KB2445403. Customers are advised to contact Microsoft Product Support referencing KB2445403 for additional information and availability of a cumulative patch. Information on how this compatibility issue may affect SecureZIP use and details on a documented work-around is available from PKWARE at https: / / www.pkware.com / documents / Eloqua / TechnicalAdvisoryOutlook2003Patch.pdf . Customers applying a cumulative Outlook 2003 patch for KB2445403 from Microsoft do not need to consider this work-around. Please contact PKWARE Product Support for information or assistance with this problem. You can contact us on the web at https: / / www.pkware.com / support / desktop .

There are several ways to create a .ZIP file in PKZIP or SecureZIP, including:Using the Create New Archive wizard;Using the drag and drop method;Using the Add Files dialog; orUsing the right-click context menu on one or more selected files in Windows Explorer.All of these methods are explained in the help section on zipping files.

The simplest way to compress a folder and all its subfolders is to select the folder in Windows Explorer and drag it into the main PKZIP window. Alternatively, you can zip folders and subfolders from the Add Files dialog. In the Compression Options dialog, first set the options Include subfolders and Save folder name: Relative path. See the help section for information on other settings you can make in the Compression Options dialog.

There are several ways to extract a file from a .ZIP in PKZIP, including:Using the Extract from Archive wizard;Double-clicking on an archive;Using the PKZIP Open dialog; orUsing the right-click context menu on a selected file in Windows Explorer.

You can add multiple files to an archive in all the same ways that you add single files, including:Using the Create New Archive wizard or the Update Existing Archive wizard;Using the drag and drop method;Using the Add Files dialog; orUsing the right-click context menu on one or more selected files in Windows Explorer.

There are two ways to have PKZIP add files from multiple folders in a single operation:In the Add Files dialog, build a list of files selected from different folders. You select files to add to a list in the same way that you select files to add to an archive; but, when you add files from a list, PKZIP waits until the list is complete and then adds all the files in one operation. See the help topic: Add Files from a List.Turn off Auto-Save and add files with drag and drop. The Auto-Save feature will save an archive automatically anytime you change the archives contents by adding or deleting files. When the feature is turned on (as it is by default), you do not need to manually save an archive each time after you change it. If you want to make several changes to an archive for example, add several different sets of selected files you can turn off Auto-Save so that PKZIP runs in delay-save mode. To turn off Auto-Save, right-click an empty area in the middle of the PKZIP main window and uncheck Auto-Save in the context menu. When Auto-Save is turned off, PKZIP creates an internal list of any changes you specify, but does not make the changes until you manually save the archive (or turn Auto-Save back on). Until then, PKZIP highlights names of files that you add, update, or delete in boldface and flags the files with special icons. When you save the archive, all of your changes are made in one operation.

PKZIP and SecureZIP v12.5 allows you to define a three-letter extension for your ZIP archives, either as a default (in Mail Options) or in individual email messages. See the help topic: Using Alternate ZIP Extensions.

WinZip is not a PKWARE product. PKWARE invented and continues to innovate and evolve the standard for ZIP data compression. Similarly, we invented and set the standard for SecureZIP. For more information on PKZIP and SecureZIP for Windows, please visit PKWARE Products .

If you have a virus scanning program, and you turn on virus scanning in PKZIP or SecureZIP, your virus scanner will scan for viruses in the folders to which you have just extracted files. You can configure and turn on virus scanning from the Virus Scan tab of Security Options.You can also have PKZIP / SecureZIP scan the files in an archive for viruses. (Again, you must first have configured a virus scanner.) To scan an archive for viruses, open the archive and choose Virus Scan from the Actions menu (using the Conventional interface), or go to the Extraction tab and check the "Scan for Viruses..." box. PKZIP extracts the files to a temporary location, launches your configured virus scanner to scan them, and deletes the temporary files afterward.

A split archive is a .ZIP file that is broken into smaller segments. A split archive is useful if you plan to place the file onto removable media later or want to send a large archive as an email attachment and your mail system has restrictions on the size of attachments.You can split an archive when you save it. In the Save As dialog, set the Split size control to the size segment that you want.

If you do not want to use SecureZIP to zip attachments in Outlook, click the ZIP files toolbar button in the new message window so that the button is not selected. Alternatively, you can single-click the SecureZIP tool tray icon. An x will appear on the icon to indicate that SecureZIP Attachments is disabled.

When the product asks for your license key, enter the serial number from the confirmation email you received when you purchased the software. You can also find that key in your packing slip (if you received a physical copy) or in the Online Store Help section.

The license for PKSFX is good only for the Windows Desktop graphical interface. You cannot create self-extracting archives from the Windows command line interface. If you need to create self-extracting archives on the command line, consider PKZIP or SecureZIP for Windows Server.

Currently PKZIP and SecureZIP has been tested with over 500,000 files in a single archive and our total file size limit to compress is 18 petabytes.

There are several operations for which PKZIP and SecureZIP creates temporary files:Opening and editing archived files without first extracting them: When you double-click a file in an archive to open it in its associated application, SecureZIP creates a temporary copy of the archived file for you to work on. This file is uncompressed and unencrypted while you are working on it.Updating an archive: When you update an archive, SecureZIP first creates and updates a temporary copy of the archive. When the update is completed, the original archive is replaced with the updated copy. Data in the temporary file is encrypted if it was encrypted in the archive you are updating. Similarly with new or updated files for the archive: they are encrypted in the temporary file if they are to be encrypted in the updated archive.Creating a spanned archive: A temporary file is created to span an archive in segments across multiple discs or other media. Data in the temporary file is encrypted if it is to be encrypted in the final archive.

This date should restore by default when you unzip files. However, if you downloaded your .ZIP file from another computer Windows may have file blocking set for the file. This will prevent the original time and date information from being preserved when unzipped. To correct this open File Properties for the .ZIP file within Windows. Choose "unblock".

SecureZIP does not operate in FIPS 140 mode by default. To enable this mode, choose SecureZIP Options and select Security-General. Select the setting for Encryption Algorithms to Use FIPS 140 mode. Use SecureZIP Enterprise to lock this setting using policy manager.

No, and we strongly recommend this Windows policy setting not be used when trying to achieve FIPS compliance. Turning on this setting is often cited as leaving user systems completely unusable. Customers frequently report they must immediately disable this setting because of the disruption it causes. Common examples are applications cease to run, network connectivity may fail, and many websites become unreachable. PKWARE provides a FIPS MODE setting that ensures the use of FIPS 140-2 validated cryptography and that does not require using this Windows setting. FIPS 140-2 validated cryptography is used only within SecureZIP and does not adversely affect any other system functions.

SecureZIP has been tested using the National Institute of Standards and Technology (NIST) FDCC test images for Windows XP and Windows Vista. SecureZIP operates correctly on FDCC configured desktops.

SHA-1 is scheduled to be deprecated by NIST as FIPS-compatible after 2010. SecureZIP v12.5 in FIPS mode will not sign files or central directories using the SHA-1 hashing algorithm.

Yes, existing certificates using the SHA-1 algorithm will be valid until they expire.

NIST is also scheduled to deprecate 3DES-112 (also known as two key 3DES) after 2010. SecureZIP with FIPS mode turned on will not extract files encrypted with this algorithm. By default, SecureZIP uses the FIPS 140-compliant AES-256 algorithm.

SecureZIP has been tested using the National Institute of Standards and Technology (NIST) FDCC test images for Windows XP and Windows Vista. SecureZIP operates correctly on FDCC configured desktops.

Your computer manufacturer can tell you whether the processor is 32-bit or 64-bit. The System page in your Windows Control Panel should also tell you. This page can also help you identify the type of Windows operating system you have:http: / / support.microsoft.com / kb / 827218

If you are using a 64-bit version of Windows, we recommend installing the 64-bit version of PKZIP / SecureZIP (in version 12.4 and later) to make the most effective use of your Windows environment. If you are running Windows XP, we recommend you update to a newer version of Windows.SecureZIP v12.3 included a 64-bit Explorer shell integration module. To complete the setup for 64-bit Explorer integration, after installing SecureZIP v12.3, run the "Install 64-bit Explorer Integration" option from the SecureZIP entry on the Windows Start menu.SecureZIP versions 12.2 and earlier operate on 64-bit versions of Windows, but they do not integrate into the 64-bit version of the Windows Explorer. Run the 32-bit Explorer for this integration by selecting Run from the Windows Start menu. Enter %systemroot%\syswow64\explorer into the Open box and choose OK.

SecureZIP v12.4 is the first release for 64-bit Windows. The 64-bit SecureZIP installer should uninstall any existing installation of SecureZIP v12.3 or earlier before installing v12.4. If you have already installed the 32-bit v12.3, you will need to uninstall the 64-bit Explorer Integration application manually before installing SecureZIP v12.4.

Yes you can, however, the convenience of PKZIP / SecureZIP integration with the default Windows command line shell will not be available. If you are using a 64-bit version of Windows, we recommend installing the 64-bit version of PKZIP / SecureZIP to make the most effective use of your Windows environment.

No, 64-bit PKZIP / SecureZIP will only install and run on a 64-bit version of Windows.

Yes, PKZIP / SecureZIP v12.5 Office Integration will work with both 32-bit and 64-bit Office applications.

You can create PKSFX files using the 64-bit versions of PKZIP / SecureZIP for Windows Desktop, however, only 32-bit PKSFX files are provided at this time. This ensures that PKSFX files you create will run on the widest range of target systems.

SecureZIP v12.4 and later includes support for creating and opening ZIP files using the LZMA compression algorithm.

SecureZIP v12.4 and later includes support for creating and opening ZIP files using the PPMd compression algorithm.

SecureZIP v12.5 includes support for opening ZIP files using the WavPack compression algorithm.

Thank you for your interest in SecureZIP Express. PKWARE offers our customers high quality products to help serve security and compression needs. SecureZIP Express has successfully provided a means for users to obtain the advanced security available through personal digital certificates and SecureZIP. We have discontinued the limited-time offer of SecureZIP Express as we focus on new initiatives in providing interoperable, easy-to-use security solutions.

Yes, you may continue to use your installed copy of SecureZIP Express for as long as you choose.

Support for re-installing SecureZIP Express was discontinued at the end of December, 2009.

SecureZIP v12.4 and later Office Integration does not support compressing or encrypting files with Outlook Express or Windows Mail, as Microsoft has discontinued these products.

Below is a screen shot of how the program may look, this is caused by a bad installation or a previous version not being removed properly. To correct this issue, go through Add / Remove programs and remove SecureZIP for Windows. After removing the program, make sure all folders and files are deleted. Then REBOOT the machine and re-install SecureZIP.

All file times will remain true to the Operating System; there will be no effect to our product based on DST.

No, the Authenticity Verification feature of PKZIP programs has been discontinued for a number of years. This feature was originally provided to registered PKZIP for DOS users. It allowed them to embed an identifying string within their copy of PKZIP. When they created ZIP files this early form of a signature would be included within each ZIP file they create. It would then be verified on extraction to show the identity of the creator. SecureZIP offers a much stronger alternative to this capability through the digital signing feature. Digitally signing a .ZIP file using a users verified digital signature provides for authenticated identity reporting to the recipient and ensures the content of the ZIP file has not been altered. Digital signing is the recommended method to provide authenticity and identity verification to your .ZIP (and OpenPGP) files. A digital signature is applied to ZIP files using your X.509 digital certificate which can be obtained from certificate sources such as Symantec or Comodo. Other certificate sources can be used. A digital signature is applied to OpenPGP files using your RFC 4880-compliant OpenPGP key.
