Verify Hash File

The hash file is a way to ensure that the file you downloaded has not been corrupted or changed.

To verify the Hash simply run this command from a cmd prompt on your PC on the file that you downloaded.  The SetupHash.txt will contain the Hash on the second line.  This should match the SetupHash_V2.2.0.txt that you downloaded.  If the Hash does not match then the file is corrupted and should be re-downloaded.  If the problem persists please use the Contact us page to report the issue.
