!!! Actually this is win 2K driver. !!!
(Sorry for my poor English)
Installing it on WIN XP is a little tricky - but it WORKS (I did it and it works great)
1. Download the driver.
2. Execute it till the point it extract all files - don't continue from there.
3. Locate the directory where file where extracted (under %TMP% or something) and copy all of them to other place.
4. Cancel the executable.
5. Now using add/remove hardware or device manager - install scanner driver form the location you copied the files to. (Look for ...\OT1Drivers\OS\Scan_ENG.inf or ScanEng95.inf)
Again, i did it on my XP and it workes great.
