Cannot TWAIN CanoScan LiDE 500F

I recently removed most of my software from my pc to clean up from a virus and when I reinstalled my CanoScan LiDE 500f, it will not twain. I've tried uninstalling all the software it came with and then installing it again. I've downloaded new drivers for it, but for some reason it will not twain. Any suggestions?

    I also had to rebuild the operating system/software on my PC laptop and the CanoScan Toolbox won't recognize the scanner. Windows XP recognizes it and the buttons on the scanner will start up.

    I recently had the Windows XP operating system rebuilt on my Dell laptop and now the CanonScan toolbox won't recognize the device (error: Unable to select TWAIN source). I have uninstalled and reinstalled the software also.

    Installed the toolbox and TWAIN software online - but no source shows up in the box when attempting to scan, copy, etc. There is no response from the scanner. Utilizing the buttons on the scanner also does not elicit a response as well. Do not have the CD software (cannot find it) so did this from the online source that is identfied here as well. Already ok w/ a current driver. Wanting to figure out how to get the computer to recognize the scanner - to show it in the source window for selection when utilizing the toolbox.

Why can I not run my Lide 500F scanner with a Windows 7 PC?

I have a cannon flat scanner 2000 & I came across this once before, I uninstalled all the cannon drivers then re-started the PC & next instead of using the Cannon drivers, I used Microsoft's Drivers & it's worked fine ever since.
I hope this works for yourself as well. Best Wishes. Malcolm.
