I always have the error "the class installer has denied the request to install or upgrade this device" when installing the scanner on a Brother MFC 8420 on Win Xp Pro SP1. I can print with the drivers that were on the CD with the device, I can install paperport but when it detects the scanner there are errors
I wonder if there ar some security issues with that error?
How Can I install the scanner?
I removed my Anti virus just in case.
