Authored by Caleb Scharf April 20th, 2022 7106 views 2 likes KB955722

Description

Ansys software has many licenses and features/increments (specific functionally within the software). These licenses can be checked out and used in many different ways and may have been customized based on a customer's specific scenario. If a user is unable to checkout an appropriate license, a license is unavailable or is experiencing other license checkout related issues, it is common to have to reset the user license preferences back to default. In some cases it may be necessary to set the the server/site license preferences back to default.

Reset Server/Site License Preferences (Applies to all users)

If you are experiencing a license checkout related issue affecting multiple users, and it's not a connectivity/firewall issue‍, resetting the Server/Site License preferences may resolve your issue.

All Versions - Via GUI

The preferences set on the server will be pulled by all users at the time the user first connects to the license server. If the Site Preferences change after that point, the user will need to manually reset their user license preferences locally to obtain the new settings.

These steps need to be performed on the license server.
Windows Search > search for Server ANSLIC-ADMIN Utility > right click and select Run as Administrator.
Select Set Site Preferences > choose Specify Product Order > choose 12.0 and higher > Ok
From the dropdown select Solver > select Reset to Default
Repeat this stop for PrepPost, Geometry and HPC
Restart the license server for changes to take effect.
