Hello. For some reason, when i try to open the HEK setup .exe, i get an error message telling me that it is not a "valid Win32 application".
How can i avoid this?
Please help me, i'm desperate to start fiddling around with the HEK!!!

Sounds like you edited the setup.

1. Did you re download the setups?
2. Did you try to install Halo CE Before HEK?
3. Where did you dl the Setupds from
4. What are your sytems specs (svp2, xp etc)
5. Did you restart your computer? (works miracles sometimes)

THanks, I'll try those things.
