Did you upgrade, or was it a fresh install?
Did the games that currently don't work, exist on the system prior to upgrading?
If you download a new game exe from here or YYGs does it work?
If you recreate an exe from your original source, does it work? How about a game with just an empty room?
These are the things that you should be trying and updating us on, simply saying some work others don't is meaningless.
Nope, creating a blank room and saving its executable still makes the error that it is corrupt. The same if I try to create an executable of my own games.
I did an update, not a clean install. All the games were on my system before which was Vista, they worked perfectly.
