Obviously, Office is loaded on my computer because it starts up after going through the messages and canceling them out. I cannot for the life of me find our Office discs (we just moved and everything is all over the place). After I cancel it out a couple times, the Office program I want runs, but it goes through this 'installer' and then the error message each time. When I try to run Microsoft Office, I get the 'A required installation file SKU111.CAB could not be found'.
