Nintex Automation K2 (5.8) Fix Packs

Important Security Update:
An important security hardening update was addressed in Fix Pack 33. We strongly recommend that all customers upgrade to this version or a later version to ensure you benefit from this security enhancement.

Deprecated functionality and components

Google Chrome intends to deprecate and remove XSLT support from the browser for security reasons. As a result, you may need to migrate your code before support is removed in November 2026.

Fix Pack 35 contains the XSLT support for Nintex Automation K2 (5.8). If you cannot install the fix pack on time, you can use a workaround described in XSLT Deprecation in Google Chrome Browser | Community.

.NET 10 Support Now Available

Installer Nintex Automation K2 (5.8) (5.0009.1000.1) is now available here (LINK) and includes support for .NET 10.

Please ensure that Fix Pack 35 is also installed, as it includes additional .NET 10 support.

IMPORTANT:

If you perform a reconfigure without reinstalling the fix pack, users will not be able to log into Nintex Automation Designer/Manager/Workspace/Runtime after the reconfigure completes and the below error will occur:

“HTTP Error 500.19 - Internal Server Error”

NOTE:  If you have client tools installed, please do a manual IIS Reset after installing the Fix Pack.

Prerequisites and Dependencies

The Fix Packs are only compatible with Nintex Automation (5.8) products. Because Fix Packs are cumulative, each new Fix Pack contains the updates and fixes that were included with the previous Fix Pack releases. Nintex Automation (5.8) must be installed first after which the latest Fix Pack must be installed. To determine which cumulative update or fix pack has previously been installed in your environment see https://help.k2.com/kb000426.

Note: Upgrades from versions older than K2 Five (5.5) are no longer supported. Only upgrades from K2 Five (5.6) and Nintex Automation (5.7) are supported. If you need to upgrade to Nintex Automation (5.8) from an older version, you must first upgrade to K2 Five (5.6) or Nintex Automation (5.7).

Installing the Fix Pack

To install the Fix Pack, run the Fix Pack installer on every machine in your environment where a Nintex Automation product or component is installed, including desktop machines that have Nintex Automation Studio or Nintex Automation Designer for Visual Studio installed. The same installer is used to update the specific Nintex Automation products and components that are installed on that machine.

• Backup your Nintex Automation database.
• Download the Nintex Automation (5.8) Fix Pack.exe.
• Double click the .exe file and select a location to extract the installation files.
• The Update window opens. Click Change if you need to change the Nintex Automation database. Select the correct information and click Accept. Click Update to start the installation.

• A warning is displayed if a backup of the Nintex Automation database is not found. Create a backup before selecting OK. Click OK on the warning window to continue with the update. Click Cancel if you want to create a backup first.
• After creating the backup, you can click Update again on the Install window. If a backup for the Nintex Automation database was recently performed, the installer shows you the date and time of the last backup.
• Click OK to continue with the update.
• Wait for the update to complete, and then click Finish.
• If you need to view the installation log file, open it from the link at the bottom of the Update window or you can locate the InstallerTrace[date].log file in the %temp%K2 Setup Log folder.

Rollback Instructions

• To roll back the Nintex Automation (5.8) Fix Packs, uninstall Nintex Automation from your environment.
• Re-install Nintex Automation Five (5.8).
• Re-install the Fix Pack you had installed prior to this rollback.
• Delete the database created when you re-installed it.
• Restore the Nintex Automation database using the backup made before the update.

You can also restore the Nintex Automation database before re-installing Nintex Automation. When you re-install, you can just point to the restored Nintex Automation database.
