Failed CreateProcessAsUser / incompatible Windows compatibility override

Checks and expected results

Before you repair it

• Capture CreateProcessAsUser or the exact launch error if present.
• Check Compatibility settings on the actual iRacing executables and compare them with the shortcut paths.
• Preserve the current settings before removing only the administrator or legacy compatibility overrides implicated by the failure.

How to confirm the result

Relaunch through the usual supported UI path and retry a test session. If the failure is unchanged, retain the before-and-after settings for further diagnosis.

Repair limits and when to stop

This is a targeted compatibility change, not a blanket instruction to run Steam or Windows applications as administrator. Other applications’ compatibility settings remain outside the repair.
