chmls unblock <exename>

Keep a backup of the .exe just in case.

Or try to see if there is an "unblock" in the properties of the .EXE.

If so it is because MSIE adds a note in a secondary stream that it is
downloaded content from an untrusted zone. Your IE zone configuration might
be a cause too.

I've seen report that it sometimes also happens when copying of (non Windows
hosted) shares, but haven't seen that confirmed.

It started with XPsp2 IIRC.
