I didn't see any bug report about this in beta.f-secure.com, nobody from our side has probably not even noticed this thread until now. In any case, error 51 is typically caused by DeepGuard code injection into games and some games don't like it. If we know executable to be safe, then that doesn't happen, so easiest way to solve this is submitting the game executable as false positive here: https://www.f-secure.com/en/web/labs_global/submit-a-sample. In the additional information just say that it's causing error 51 for the game with steam when DeepGuard is enabled and our labs guys will fix it.
Hi, thanks for posting that info about Deepguard.
I tried adding the two exe files but no joy, then added whole ww2 folder in steamapps/common but no joy. Then thought, 'sod it' and excluded entire steam folder and what do you know, it worked.
