Vista - Epson CX4800 -- error: Windows failed to install drivers. Cannot find file specified

My Epson 3-in-1 CX4800's scanner stopped working (copying and printing is fine). I have tried (with live phone help from Epson) several times to reinstall scanner drivers, but, even after downloading them, the message comes up: Windows failed to install drivers. Cannot find file specified. Epson had me find the file folder, click on the file (which obviously was there), try again, but same message. They finally said it is an OS issue, mine is vista home premium 32 bit. Can someone help me with this? Thanks a lot!

have you tried to uninstall the drivers and program, reboot the pc, than try to reinstall the dirvers and program?

Thanks for your help. I believe all Epson had me do (if this is possible) is uninstall the scanner drivers, reboot and reinstall. However, I do not have the disc; I downloaded from the Epson website. Each time I tried, the download appeared to be successful; then i rebooted, and attempted the actual installation, which failed. Also, when I go to device manager (after rebooting and after the installation fails), the scanner is listed under "other devices", and has an exclamation point next to it, stating "The drivers for this device are not installed. (Code 28) The system cannot find the file specified." Thanks!

When you reinstalled did you have the scanner connected?
Install the software without the scanner connected.
Now when the scanner is connected it will (hopefully) see the drivers.
If you end up with the red exclamation mark then you need to manually tell device manager where the drivers are.
I have the DX4400 and DX4450 and the drivers are in system32 and twain32

Thanks! I tried that also...no luck. And, I just tried to install my son's Lexmark 3-in-one, and after following all directions, the SAME error message---"system couldn't find the file specified". (Also done with scanner not connected.)

does vista find the hardware?

if vista does not it could be a usb problem
