32 bit application won't run on some Win7 64 bit machines?

Well, it looks like the error you're seeing is being generated by the HooksApi::Initialize() method, so without seeing the code it's impossible to tell what's going on From the error message tho', I would guess that an environment variable, or some other environment setting is being tested, and is not being found The "author of the program" should look at HooksApi::Initialize() and to see what causes that error to be generated.
