What you will need to do:
  1. Uninstall RTW and delete your RTW folders. Make sure you still have the 1.2 patch installer and the EB installer, though!
  2. Install RTW from the CD's.
  3. Apply the 1.2 patch. If it says that 1.2 is already installed, it means that your computer doesn't realise that the patch had been uninstalled due to a programming error on CA's part. You can download the 1.2 patch without the installer from this page (here's a direct link to one of the download locations). When that's downloaded, run WinZip and extract to your RTW installation directory.
  4. Run the EB installation program and point it to your RTW installation directory.

There you go! If something doesn't work, let us know.
