Same here - as long as you remember to install and run it as admin, TRS2006 will run on Windows 7 (32 and 64-bit)

EDIT: Most of the time, Windows 7 is smart enough to detect a setup program and will usually throw up a UAC box and run the installer as admin anyway. If it does not, you can always go into the CD folder, right click the setup file (usually setup.exe) and click Run as administrator.
