Posts from It says that the original version cannot be found. Auto-translated

I bought the original Heroes game – played through everything, bought the official expansion, everything seemed to be working fine, with all the updates and everything – and it says “unable to find the original version of the game.” What the heck is going on? Does anyone know?

Clean the registry, reinstall the original game... It should help.

Where can I clean it? Thank you...
