Cheat Engine

[Frostbyt3]

I'd just like to know if anyone in this section can help.

I've been slowly hacking away at my games tile engine, separating it into a DLL on my Dev WinXP install, and it was working fine.

Then WinXP Corrupted. I do have the files still though, so all is well.

But this time, I chose 64bit vista, and love it, but this one problem.

Whenever I load an assembly that hasn't been explicitly told to run with
any type of program, 32 or 64 bit, I get a BAD IMAGE FORMAT error.

Has anybody got any clue at all how to get these to work? I've got a few
to work out-of-the box, but one or two aren't working.

EDIT:
Forgot to say, using visual c# 2008 express, about to get 2008 pro, if that makes any difference.
