There are no drivers for this scanner (to use with Vista). This scanner is outdated and Epson has discontinued their support for this scanner.
New technologies emerge with time and this causes old ones to become obsolete. There are new scanners available with much better resolution and scanning speed.
I understand that this scanner has, and maybe still, doing your job but please try to understand that only the original equipment manufacturer can provide the drivers; if they can't probably no one else can.
However, drivers for Win XP are available for free download. Please click here to visit the download website.
Vista has a large database of generic drivers. Maybe it will pick this scanner up and install so you are still be able to do basic scanning.

You maybe able to download the Vista driver from the Canon WEB site from their support/download page.

Cant find such a scanner, are you sure of the model "performance", If it is not Vista compatable, ie if Epson have not released a Vista driver, then it is not going to work with Vista.

See Epson web and download driver if available, if not change scanner or operating system or purchase software

Check your Epson product CD to see if it already contains Windows Vista drivers. If the CD indicates support for Windows Vista, follow the instructions that came with your Epson product to install your driver and other software.

If your Epson CD does not indicate support for Windows Vista, DO NOT INSERT YOUR EPSON PRODUCT SOFTWARE CD IN YOUR WINDOWS VISTA COMPUTER because the setup program is not compatible with Windows Vista. Instructions for installing additional software from your CD may be available with your driver download.

Note: If you already have ArcSoft PhotoImpression™ 5 installed on your Windows Vista computer, you may need to install a "patch" program. Go to the ArcSoft website to download and install the patch.

Products that are not Vista compatable are not capatable with Vista, who would figure hey!!

Although you didn't specify the operating system you're using.

If you are using Windows Vista, some people have reported success using Windows 2000 drivers on Vista.

If you are not using Vista, choose your operating system from the list, and download.

Be sure to UNPLUG the scanner from the PC before installing the software. ONLY plug it in once the on-screen instructions tell you do so.
