If you use the exe we posted, then cheats will be disabled. You can use the original exe if you want to play against someone with cheats enabled. You are of course free to install any news maps with the old exe if you want to play them that way, but you have to make sure all players have the same versions of every file, or you'll likely run into problems. They can range from game version errors when trying to join games, checksum errors when starting games, or out of sync errors when playing. (Or possibly just plain crashing if you get things just right).
Anyways, the first error will prevent you from playing with the original exe against people with the downloaded one. So there isn't a way to just get around the patch by using a different exe. (Even if you patched it yourself to try and get around it, the last errors will still get you).
