Office 365 Problems

Take a look at the following:

1. Disable Hardware Graphics Acceleration

• • Open any Office app (if possible) → File → Options → Advanced → Scroll to “Display” → Check “Disable hardware graphics acceleration”.
  • If you can’t open the app, try this via registry:

[HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Common\Graphics]
"DisableHardwareAcceleration"=dword:00000001

2. Run System File Checker

• • Open Command Prompt as Administrator and run:

sfc /scannow

• • This will scan and repair corrupted system files.

3. Check for Windows Updates

• • Make sure your system is fully updated. Sometimes Microsoft releases hotfixes shortly after problematic updates.

4. Rollback Office Update

• • Run this command in an elevated Command Prompt to revert to a previous stable build:

cd %programfiles%\Common Files\Microsoft Shared\ClickToRun
officec2rclient.exe /update user updatetoversion=16.0.19231.20116

• • Then disable automatic updates temporarily to prevent reinstallation of the problematic build.

5. Check Event Viewer

• • Look for crash logs under “Application” in Event Viewer. DLLs like d3d11.dll or react-native-win32.dll have been implicated in similar cases.
