I'm using Epson Print CD version 1.60A on my Windows Vista Ultimate 64bit
and Windows 7 Ultimate 64bit with no problems at all. I also have the Epson
Print CD version 2.00.00A installed but I never use it as I like the older version
a lot better.
What version are you trying to use on your system and did you remember to DL
and install the Epson Easy Print software utility also?
The printer driver I'm using on my Epson RX595 was for Vista 64 but it works just
fine with Win7 64 bit also and the printer I was using before the Epson R220 the
driver for it worked just fine with both OS's too.
