I have vanilla RTW 1.5 installed and I am playing certain campaigns on it, but I want to play EB too, as far as I understand from the installation guides EB is more like a total conversion rather than a mod because it requires a clean installation of RTW 1.5, which means I will either play play vanilla or EB.

I tried to make a seperate installation of RTW but it does not let me do it.

Could you please help me on this issue, how can I play both the vanilla game and EB.

Thanks in advance.
