Prerequisite Requirement Checking and Reporting

Upon launching Discovery after installation, prerequisite checking occurs automatically to ensure there are no installation issues that may lead to unexpected behaviors or failures. The results of these checks are reported in several ways:

• When you launch Discovery, a dialog box reports any missing or out-of-date prerequisites that were identified.
• Results of the prerequisite checks are captured in the Discovery application log.
• The SID reports any missing or out-of-date prerequisites that were identified when Discovery was launched, as well as results concerning prerequisite checking specific to the Explore and Refine stages.

Reporting Issues to Ansys Customer Support

1. If you encounter issues running Discovery, follow this procedure:
2.  Open the Windows command prompt as administrator.
3. Run this command: “/Framework/bin/Win64/Ans.DriverSetup.exe” –check-system-compatibility
4. Capture the output of the command and include it when contacting Ansys customer support.
