Diablo 1 HD Hellfire Mod | Awake

Hello,
i want to play Diablo HD, but when i copy content from mod folder to diablo folder and i want to open belzebub.exe, its writes System error:

The program can't start because MSVCP100.dll is missing from you computer. Try reinstaling the program to fix this problem.

But Diablo.exe i can open and play...

Do you know, what is that?

Thank you for advise, i want to play Diablo HD too much..

Are you sure you installed everything required?
Especially .NET Framework 3.5 and Microsoft Visual C++ 2010 Redistributable which can be downloaded form MS website.
