Not a valid win32 application

[ryan0302]

I'm trying to mount/install GTA 4 but it wont work. I made an ISO image off the disc i had for it (my disc drives dont work so i have to do it this way) and mounted using magic disk and daemon tools but neither of them did the trick. When i try to run the setup after mounting it, it just says "not a valid win32 application". I already searched all around for a solution but can't seem to find one. Thanks in advance.

Seems the ISO is corrupted.
I'd try to create a new image.
