Deleting the folder in AppData solved my problem.
1.) If you can’t see AppData, turn on Show hiddel files, folders or drives and disable Hide protected Operating System files (recommended)
2.) You can do this by in Win7 (and Vista) by opening an explorer window, hit “ALT-T” chose Folder Options then go to the view tab.
3.) Select show hidden files,folders and drives. Then click ok.
4.) Now you can see the AppData folder . Go into AppData folder select the Local folder and Delete the Microsoft_Corporation folder.
