I found an expired thread on this subject that was written a few years ago. I followed mastersnoopy's advice and it worked out great to get into my Microsoft Office 2010 programs, but I'm still getting the same message every time I open a specific file such as a Word document or an Excel spreadsheet. I tried to follow the same steps (more or less), but they didn't work out for specific files. Can someone please tell me how to get rid of this annoying message when opening MS Office 2010 documents. Thank you!
