If that error message is exactly as shown (and I doubt it), then there is something seriously wrong with the path as that should probably be "c:\program files (x86)\gsak\gsak.exe" (being precise in such error reports is important, as small details sometimes make all the difference).
However, I think the more likely reason for the error is your virus scanner. Make sure that you exempt the gsak folder and all subfolders from life/real time scanning and add gsak.exe to your whitelist.
