Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Hi,
Since both Word and OfficeClickToRun.exe fail with error 0xc000012f and point to different Click-to-Run DLL files, this looks more like a corrupted Office Click-to-Run installation rather than a Word-specific issue.
First, open Command Prompt as administrator and run:
DISM /Online /Cleanup-Image /RestoreHealth
sfc /scannow
Restart Windows afterward.
If the error remains and normal Repair/Uninstall still cannot run, I recommend completely removing the damaged Office installation and then reinstalling Office.
Please let me know whether DISM or SFC reports that corrupted files were found and repaired.
