Windows Installer Cleanup that will remove the reminants and the registry items. Google it.
I have been attempting to reinstall the software for my Epson Perfection 1260 scanner on my Acer Aspire 1640 laptop. All components install (twain, photo impression, reference guide) until it gets to the "Smart Panel".
I got a notice that components of this program are already installed and need to be removed. I went to the Control Panel, Add/Remove Programs - sure enough, there's Epson Smart Panel. Clicked "remove" -now I get "install shield wizard has finished maintenance" - click finish button - and Epson Smart Panel is still listed. It won't go away!! I've deleted, individually, every file I could find pertaining to Epson and still can't get rid of it so I can reinstall. HELP! [In the meantime, I've also deleted all the other "parts" (twain, photo program, reference guide) using Add/Remove and they go away as they should.]
