Hi Rylan,
As I understand you are getting an error Office is busy when you try to access the Word program. Let me assist you with the issue.

If the repair process fails and the issue is accross all the Office applications, then remove the Office program and reinstall it. Check if it helps fix the issue.
Run the fix it from the article below to remove the traces of Office completely from the computer:
