Hi list, I've been trying to install a plustek optibook 3600 on a windows 7 64 bit machine. I keep on getting the error "an32plus cannot find some software components - please reinstall your driver software. I am using the latest version of the driver (v4.0.1.0) I've been installing as the administrator. I've uninstalled using the driver installation program and control panel "programs and features" and then reinstalling using either the driver setup file or using the device .manager Has anyone come across this problem? Thanks David
