Solidworks launch problems

Good morning,

  Last night I turned my computer off with no problems. Then, when I turn my computer on the following morning, windows is repairing. I try to launch Solidworks, but windows installer tries to install it. I have no idea what the problem is, as I cant find anyone with similar problems. I am running the student version and have used this program normally the day before. I have tried to fix the problem using windows installer, and it says drawcompare.exe is not installed. Then there is an error message.

Please help me, thank you for your time,

Sincerely,

Yelizar Dergachev
