The DTP 94 does work with Win7 64 with ColorEyes software. You can download Coloreyes free 10 day Demo. I had to jump through some hoops to get it to work. The second link below will take you to the Coloreyes forum, if you encounter problems. Make sure it works with the Demo before you purchase the software.
