we have 2 pentium computers, both using windows xp. on one whenever we try downloading any exe files the download freezes about half way through and when it finally finishes we get a "not valid win32 application" error. when we try the same download on the other computer it goes through just fine. we use a wirelees connection to a router to access the internet. we have run ati spyware and defrag software to no avail.

Is "not valid win32 application" the full error message?

Here is a general page on that error:
