Operating System Not Supported

I have the Passport Essential SE 750 GB, when I try to open View and Restore,  I get this message; WD Anywhere Restore cannot be run under this version of windows.  I have Windows 7 64 bit, does anyone know what I can do, I want to re install my operating system on my computer, but all of my data is in my WD Passport. 

Are you installing from the CD or the one from the net? It’s possible the one on your drive is out of date…
