Then you can make a new install in another map. Repeat this procedure with VI and patch 2.1, and you're done. This is how I did it.

However, it should also be possible, if you still have a clean (patched, but no mods) install of M:TW + VI, to just copy the contents of the M:TW folder to a second one and install the mod there.
Ok thanks, but I have another question, I have MedMod so I can uninstall it, could I still do the copy thing?
