I installed it and ran it on my C Drive. It found over 40,000 deleted files-not sure if that's normal or what. Anyway, no matter what I do, even if I restart my PC before running it, it always stops at 99% at the first stage. It will say 0 seconds are left, but then after some minutes go by, this will turn to a 1 and so on. I think a deleted log file may be what is keeping me from opening any Microsoft Office programs without being prompted for an installation. I really need to get whatever I deleted back, but nothing has worked. This was my last hope.
