You can use the Upgrade option during Windows 7 installation, which preserves your files, settings, and programs, only if you're currently running a 32-bit version of Windows Vista and you want to upgrade to the 32-bit version of Windows 7. Similarly, if you are running a 64-bit version of Windows Vista, you can only perform an upgrade to a 64-bit version of Windows 7. For more information, go to Upgrading to Windows 7: frequently asked questions on the Windows website.
If you want to move from a 32-bit version of Windows to a 64-bit version of Windows 7 or vice versa, you'll need to back up your files and choose the Custom option during Windows 7 installation. Then, you'll need to restore your files and reinstall your programs. For more information about performing a custom installation, see Installing and reinstalling Windows 7‍.
Notes

• To install a 64-bit version of Windows 7 on a computer running a 32-bit version of Windows, you'll need to start, or boot, your computer using a 64-bit Windows 7 installation disc or files.
  
• If you start your computer using a 64-bit Windows 7 installation disc or files, but your computer isn't capable of running a 64-bit version of Windows, you'll see a Windows Boot Manager error. You'll need to use a 32-bit Windows 7 installation disc or files instead.
  
• Windows Easy Transfer can't transfer files from a 64-bit version of Windows to a 32-bit version of Windows. If you're running a 64-bit version of Windows Vista but you plan to install a 32-bit version of Windows 7, you can move your files to an external location manually or use Backup and Restore in Windows Vista.

I think you answered your own question here ... if it will not work on 64 bit ... well ... you cant install it on 64 bit.

Might you have a second computer in the house which you could add to a network - attach your printer to that qualified computer and then have it as a network share?

have you checked at Canon for a 64 bit driver?????

I think the problem is..... Magix is compatible with XP 64 bit but not with Vista or 7 64 bit, not much 3rd party software is.

check if you have the 32 bit vista or a 64 bit vista os.
if you have the 64 bit vista on the computer try to install a 64 bit vista compatible printer driver to make it work.

I'm not sure if this will work on the lide 20. I have an lide 35, and there are no 64 bit drivers for it. I downloaded and installed the drivers for the lide 60, told the computer to manually find the lide 60 drivers for my scanner, and installed the canoscan toolbox for vista 64 bit. Works like a champ.

The four things that make 64-bit Vista inadvisable for ordinary users are:
1: No compatibility with old 16-bit Windows apps. This means ancient Windows 3.x software, which most people don't run any more, but 16-bit code can still pop up in the darndest places. Like, for instance, in the installer programs for other apps.
2: No automatic registry and file redirection, which is what 32-bit Vista uses to allow existing software to work with Vista's better user account security, even if the software wants to do admin-rights stuff to the registry and Program Files directory. Many apps still break in 32-bit Vista, but many more break in the 64-bit version.
3: No compatibility with existing 32-bit drivers. Everything on your computer will need a new driver. 64-bit WinXP is the same, and there aren't many 64-bit computers on which Vista won't at least install, but 64-bit Windows also has...
4: No support for unsigned drivers.
