AIP client not working - Add-in crashes Word

Dein - FocusOnBusiness 6 Reputation points

While troubleshooting with the Microsoft 365 support team, we came to the conclusion that the AIP add-in is causing the Word application to crash.

On that moment we see in event viewer this error message: .NET Runtime version 2.0.50727.9151 - Fatal Execution Engine Error (00007FFE3FAF6D4E) (80131506)

The steps we have tried:

  • Installing .NET runtime => It was already the latest
  • Disabling the add-in => Word works
  • Uninstalling AIP => Word works
  • Installing AIP => Word crashes
  • Installing the newer preview version => Word crashes
  • Installing with the .msi => Word crashes
  • Reverting an Windows update => no result = not related
  • Another device => no issues
