This printer can be installed in Windows 7 (x64, in my case). The .exe installer does not work, as it does an operating system check and doesn't recognize the OS. However, the .exe is just an executable archive file. It can be unzipped into a directory. Then, from the Devices and Printers section of the Control Panel, right click on the printer and click "Update Driver
Software". Navigate your way to the directory where you unzipped the driver files to, and Windows should take care of the rest.
Alternatively, I believe the installer program will likely be successful if you run it in Compatibility Mode and select one of the Windows Vista versions as the OS to be emulated. (I just tried starting the installer this way, which worked; I didn't complete the install because my printer is already installed).
