Nope.

What you do is (if your using a PC) go to your program files and click 'new folder', then re-name that 'new folder' to 'Activision'. Then go over to your 'Creative Assembly' folder and copy your Re-Installed RTW directory IN ITS ENTIRETY to the new 'Activision' folder. Then run the installer for Roma Surrectum In Full

It should work like a charm after that. I also recommend the 1.5 upgrade for RS, its a lot less buggy.
