It tells me the exe file is corrupted and re-download. Done that three times. The other two call my VLC video player which reads them as UNDF (undefined) file types which cannot be processed

Couple of ideas:

Make sure all three files are in the same folder.
Don't rename any of the files.
Run the exe as administrator.

All three are in my downloads folder.
None have been re-named
Ran the exe file as Administrator.
Same result: "File Corrupted"

Apparently there is no fix fo rthis. Oh well. That's $6 down the drain.
