También disponible en Español: Versiones de Windows y Office compatibles con Palisade

This article advertises compatibility specs of older and newer versions of Palisade software and Microsoft Office versions based on their release dates. This list includes all of our software versions, but only version 8 is currently for sale, all previous versions are supported with a valid maintenance plan only, if you have an outdated version and wish to upgrade, please email for subscription options and pricing.

Which software platforms or operating systems are supported by Palisade?

Palisade's latest release, 8.3.2, is supported on Microsoft Office 2013 and newer, running on Windows 8 and newer. For older releases, see the compatibility charts below.

Please note: Some functions in our software may seem to work in some Office or Windows versions that are not supported. But some functions will not work, or not work correctly, not necessarily with an obvious failure mode. We strongly recommend against running our software with unsupported Office or Windows versions, and we cannot assist with troubleshooting on unsupported platforms.

If you have an older version and need to upgrade for compatibility with Microsoft Office or Windows, please see Upgrading Palisade Software. Customers with a current maintenance agreement can receive the upgrade to our latest versions at no charge; for others please contact your Palisade sales manager.

Microsoft Office Versions:

Palisade products with these version numbers require Microsoft Office for Windows to be installed on the same computer. Mac users, please see @RISK on the Apple Mac. Lotus, OpenOffice, LibreOffice, and StarOffice products are not supported.

  • ARM Processors Compatibility with @RISK/DTS: ARM is not recommended. ARM uses less power to operate, it is usually good for devices with limited hardware resources (such as cell phones and tablets), and Palisade tools perform better with higher hardware resources.
  • Windows Server versions are not listed in the chart, because we have not done extended Quality Assurance of our end-user software with any Windows Server version. However, we are not aware of any incompatibilities between our end-user software and Windows Server 2008, 2012, 2016, or 2019 (through version 21H2).
  • Vista and newer: Right-click the installer and select Run as Administrator; simply double-clicking may not work. After installation and activation, the applications do not need admin rights.
  • All of our installers work in 32-bit and 64-bit Windows; but the RDK, BDK, EDK, and RODK must run in 32-bit processes. In 64-bit Windows, all products install in C:\Program Files (x86).
  • Windows 8.1 with our 6.0 and 6.1 installers: Please see Installing Palisade Software 6.0 or 6.1 in Windows 8.1 before installing.
  • Windows 8 with our 5.7 and 6.0 installers: Please see Installing Palisade Software 5.7 or 6.0 in Windows 8 before installing.

If you have a system with a standalone or enterprise version of our software before you upgrade Windows, please deactivate the software to preserve the license; then reactivate it after upgrading. See Transferring Standalone Software 6.x/7.x to a New Computer or Transferring Standalone Software 5.x to a New Computer for the transfer procedure.

Windows Versions for License Server Software:

Starting with release 7.5.2, our license server software requires Windows Server 2008 or newer, or Windows 7 or newer.


At the present time, Palisade products are not supported on Linux or any other flavor of UNIX.
