I noticed a minor issue regarding RUS installation on external support (FireWire 400 external DD). I'm usin an up to date XP SP3 with an up to date OS X 10.6 bootcamp. I've yet yo try but it does not seem to happen witj a standard XP install.
Constated bug : the game is not loading on map graphics for units - log shows that the engine looks for unexistant 3D files.
Solution proposed : install RUS on the Bootcamp disk (C

. This way everything is running fine.
Note that this issue is RUS specific, since i'm using an external support for AACW, WiA, Rop and NC.
