Canon Scanner – Unable to open TWAIN source
At last I am able to successfully scan my document. Rebooting, system restoring, reinstalling the app, reinstalling just the driver, running in compatibility mode, yada, yada. I added the environment variable and it fixed it.
Thanks for the advice.

Why cant Canon have this on their knowledge canoscan 4400f twain. It is disappointing that the troubleshooter should have missed something so basic – yet so obscure for people not familiar with DOS. Just want to say thanks a lot for this! When I try to use it again a couple of hours laterit keeps canoscan 4400f twain the server is busy and to switch applications, when I do that it still says that the scanner is busy.
It’s people like you that actually help the world go round. Glad that I can still use this old scanner which was a really good model.
You will be asked for the Product serial number and other information pertaining to your Product and for a ship-to location for the replacement Product must include street address. You would think that Canon’s Drive installation program would just add the correct Environment Path as part of the install process. Find the perfect lens Find the perfect lens. My scanner now works: So I can confirm, Canoscan 4400f twain 7 x 64, this advice works!
Lo and behlold, I added the C: It would just give me a “Scan failed” every time. I checked scanner operation each day since the previous “fix” and it worked canoscan 4400f twain for 3 days, now it doesn’t. Thank you very much for solving this annoying thing!
