Hi there

TWAIN is now deprecated - modern scanners don't use TWAIN any more --I had an old excellent canon photo and negative scanner which I still run on a Windows XP VM.

VUESCAN still works for a lot of these older (and very serviceable) scanners but if you don't want to pay for VUESCAN and you have an old XP system somewhere just run the XP system as a VM and your scanner should still work.

That's always a problem with technology -- companies won't support older hardware indefinitely - and even Windows 7 is going to run into lack of support sooner or later.

My advice is simply to run the XP VM -- don't worry about security or issues like that - you don't have to connect the XP VM to the internet - you just want your scanner to run. Once you've got your TIFF (or whatever output your scanner gives you) process it on W7 in the normal way.

Cheers

I thoguht that the TWAIN drivers are an alternative with more functionality to the Windows' WIA, in fact if you go on the TWAIN web site, you'll see that they are developing a more recent version.
I'm running Windows 7 64bit with the latest Canon TWAIN drivers specific to Windows 7, I think that Canon might have stuffed with Microsoft and doesn't want to pay for their loyalties so that is why the drivers have compatibility issues, unless Canon is able to tell me that they fixed the problems.
As I said the Windows WIA (Windows fax and scanner) drivers work well just they have a limited functionality.
Thanks for feedback.
