How to install RTW twice?

[Ciaran]

I´m not entirely sure whether or not the patch asks the install path, at least 1.3 does not, it installs to where the first installation of RTW is (e.g. C:/programs/games/RTW in my case). Therefore I keep that path for the vanilla version and used cpoies to install mods on them. Works fine.

I'm pretty sure I installed MM on the copy, so it should be fine.

Thanks for your help.
