I have a Visioneer OneTouch 8100 scanner that I'm trying to install. When I plug in the scanner and try to install the drivers, the drive installation wizard won't copy the files. I'll point it to "C:\winnt\inf\i386", which contains the file that it's looking for, but the dialogue window will just pop back with "\C:\winnt\inf\i386" as if it didn't find the file. I've tried copying the file to another folder and pointer the wizard to the new folder but it still returns to "\C:\winnt\inf\i386". I've installed this scanner before without problems. What's going on?
