Can't have two mods installed at once?

[Gaul]

I have and am enjoying the lovely Imperial Splendour mod but would also like to try the American Revolution mod. Not even sure if TAR as it's own folder.... But does two mods installed at once make both mods not work?

I can be almost certain that you will probably have issues if you install both at once. Although both use launchers, so it may be possible to only have one activated at a time. I would suggest copying a Vanilla Empire Installation, with one of the mods, then use the original for the other. And have one name "Empire Total War" and one named something to indicate it has one of the mods. And changing the installation you want to play to "Empire Total War" and start it with the installer as normal.
