My old Epson perfection 1640 SU scanner software doesn't work in win XP. Updates do not provide the same features as the original. I like the results I get with this scanner and prefer to use it even though I have two new all in one units. I'd like to dual boot if possible. I'm very much into graphic design and have grown used to the old epson.
I suggest trying to install the updated driver, then install the Scan Utility for Windows 2000 on Windows XP under compatibility mode:
Right click the scan utility installation file -> Properties -> Compatibility -> Windows 2000 -> Apply/OK)
Then, once installed, run the program in compatibility mode:
Find the files' .exe/run file (listed in Start -> All Programs -> Epson...), right click it -> Properties -> Compatibility -> Windows 2000 -> Apply/OK
See if that works for you. If it does, it should provide you with the updated driver, and the same scanning application you're used to.
