I have installed RTW in the C drive
The location is:
C:\Rome Total War
I can go to this location and start up RTW. But when I try to install EB 1.1 there I still get the 'Destination Directory is not valid. Please choose folder where Rome Total War was installed'. If it is not there then where is it? Wouldn't 'Rome TW.exe' be in 'C:\Rome Total War' if that is where it was installed???
I have also installed it to C:\Users\Rob\ (and tried to install EB there) and the same thing happened. I even moved it (well, dragged it) to the desktop and the same thing.

bovi, LorDBulA, the Bean, & Tellos Athenaios; I have tried to move, copy, install, and re-install RTW to the C drive. This is where is says it is and this is where I can access it. So why is it not "where Rome Total War was installed"??

At the risk of sounding totally inept, I am asking what part of what you guys are telling me am I not doing? It just seems like where ever I put RTW, I try to install EB there and I keep getting the same message about the destination directory not being valid. I have tried this about 12 different ways now and every time I get the same problem.
