Yeah, this is odd.

If the download isn't corrupt (i.e. the sha512 checksum matches that 
published), then we don't know why Windows should give this error message.

On the off-chance that it's the UPX compression which is causing this 
(as it occasionally seems to cause problems with some AV software), I've 
adjusted the build process (as I've been meaning to do for a while) so 
that the uncompressed executable is also uploaded.

You might like to try to see if the that helps with the latest build, 
which is at:
