Finally got my office tidied up and moved the scanner to the desk to my right, where pain (my Microsoft laptop) is. Connected up, installed, and ran it. It works. But it doesn't work on braindeath. Why? I've deinstalled and reinstalled and rebooted and done all those Microsoft things, but it continues to have fatal errors. Is this some case of incomplete deinstallation? One difference suggests that it is: when I installed on pain, I had to accept the usual EULA stuff. When I reinstalled on braindeath, I didn't. That suggests that at least some information remains after deinstallation. But wouldn't a bit of accurate error reporting help?
