Clean Boot Windows

Create a New User Profile

Press Win plus I. Open Accounts. Click Family and Other Users. Add new profile. Log into it. Run Access there. If it opens the old profile is corrupted.

Check Registry for Office Path Errors

Press Win plus R. Type regedit. Go to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\. Confirm all Access paths exist. If keys are missing reinstall Office.

Reinstall Microsoft Office Completely
