Canon Lide 500F will not install correctly - "Unable to open TWAIN source" RRS feed

  • Question

  • I bought a new Dell computer with Windows 10 & I can't get my scanner to install. It's acting like the driver isn't installed even though I ran the installation CD & everything is plugged in properly and all. When I open the CanoScan Toolbox I get a pop up saying "Unable to open TWAIN source" when I hit Scan.
