Hi Brirev You don't say how old your scanner is. If you have downloaded Virtual PC (XP Mode) you could and should get it to work from there either via the software disc you have or download from the Canon website. I have a Canon Canoscan 8600F which worked for me under those circumstances - which I now find works in Windows 7 (64bit) !!
I have a Canon MP 640 and W7 64 bit.Had to download 64 bit drivers from Canon. I use Photoshop CS4 and in it's 64 bit version the scanner will not use the TWAIN interface, so I launch PS CS4 in 32 bit mode, do the scanning then process in CS4 64 bit. Adobe confirm that Twain is not supported in 64 bit - not sure about other applications. If I try to scan in 64 bit CS4 only the WIA scan interface is available. What programme do you scan for?
I have the LIDE 70 and contacted Canon. They advised downloading the Vista driver. I did and all is working fine with Windows 7 64bit. They are working on a new driver for Windows 7 apparently. Hope this helps.
I've wasted many hours trawling for solutions to the LiDE 80/Windows 7 64-bit incompatibility, including trying drivers for other Canon scanners from the same era. Beleive me, nothing seems to work but the following! If your machine supports virtualisation (depends on the processor apparently, and you might need to edit settings in your BIOS) and if your version of Win7 entitles you to download XP mode, this seems to work perfectly. From within the XP mode desktop, I installed the Canon Toolbox and the ScanGear drivers, rebooted and all worked first time. I do most of my scanning to pdf, and this required me to install a second copy of Acrobat to the virtual machine. Hope this saves a few scanners from the landfill!
