It appears that 2004 will run on Win 7 without any issues, at least for our meager needs. It installed without a problem and runs files the new network. The only thing I had to do was figure out the new locations Win put the support files. Luckily there were no hard coded paths in the files. The old dog runs bettter than on our old P4s too, but I am sure quad core duos, 4 GB memory and 10k rpm drives help a little.
