RTW won't install under Windows 2003 Server

Unfortunately, RTW refuses to install under Windows 2003 Server. The installer just arbitrarily refuses to continue, even though it is newer than the versions of Windows listed in the Minimum System Requirements. I'm a little disappointed, since every other game I've encountered so far runs fine on it. Just thought I would warn anyone else that might be running 2003 Server as well.

Anyone aware of a work-around other than reinstalling Windows, by any chance? Thanks.
