here is the fix open My Documents or My Computer (Tools | Folder Options | File Types Tab). Scroll down to where .EXE would be in the alphabetical order and make certain .EXE is not there (if it is, then edit it there by changing the association to Application). Finally, select the New button, type in EXE for the extension and select the Advanced button. From the list pick “Application.” then close and then your applications will open again
