I have a machine running Windows 2000 Pro. I removed an HP scanner before installing a new Epson scanner. The Epson will not scan because the software sees another scanner still active. I have removed all possible traces of the old scanner in software but the C:\WINNT\twain_32 and some sub-directories get re-installed at boot-up and I think that is causing the trouble. If I boot WindowsXP from another drive the Epson scanner works ok. This drive has never had another scanner installed.
What can be re-installing this directory or stopping the Epson software from working?
