Registry problems when launching game(s)

I'm having issues with my registry when it comes to launching Heroes of might and magic V Tribes of the east and after fixing some of the registry issues I'm now getting a message that says "The Procedure entry point _GrannySetControlForceClampedLooping@8 could not be located in the dynamic link library granny2.dll" I would download a program to help fix the registry but I'm skeptical about those and don't know what a reliable registry program is.

Well why I was concerned about this error I get from Tribes of the east is the fact that both Heroes of might and magic V and it's expansion Hammers of Fate work just fine on windows 7 however Tribes of the east is getting the errors from lack of .dll files. plus there is the option to run in compatibility with windows XP Service pack 2 (which is my old 10GB hard drives OS) So I doubt compatibility is the issue. I'll also sift through the links and see if anything helps.

Thanks for the assist I'll update you if I find anything out.
