Winject: trying to inject cod4.dll *something's wrong* reason 3

So I tried 2 different injectors and both of them are giving me erros,
I ran them both in admin, winject says it gives me error reason 3 which is VirtualAlloc for target process failed, that's what's written in the read me.

So what am I doing wrong?

Thanks in advance

Have you tried any other dll?

try restart cod4 and open winject as admin and try if that dont work your .dll is broken
