How to Install VCMI on Windows 7?

Hello folks!

I really don’t know and don’t find how to install VCMI on Windows 7…
I have already the Heroes 3 Complete version but I don’t know how to install VCMI…

Can anybody help and explain me please?
Or do you know a website with a step by step installation guide for VCMI?

Thank you so much because I really want to use and try VCMI.
Hope someone can help me …
