The original CD does work with Windows 7 & 8, you just have to install it outside of the default location in Program Files (x86). I made a folder on the C drive, named it UBI, pointed the installer there, let it install but, not start, once it was finished installing took the disk out of the drive, installed the nocd patch, made sure it would start up, and it was ready to install GWX. That process works fine everytime. I have recently bought the SH2/SH3 release from Amazon $9.98 just to have around as a backup.
