Software 64bit unfit under Windows7

The scanner is fast and quickly, and do his work, but not with the supplied software. Not only did Canon it (? Deliberately) failed to equip old scanners with new drivers for Windows7 and Windows8, so today everyone is user constrained with an "old" Scanner and a new operating system, a new scanner to buy - no, Now also:
As a consumer I want to buy a product, then run in the worst case a setup and then everything has to run - does not do it that, then the usabiltity testers have screwed up something.
Long story short: software from Canon announces under Windows7 64bit that the driver is not installed properly and should be reinstalled. At the driver it is not, no error message, everything tutti. When you start "Windows Fax and Scan" This allows the scanner trigger problems. Hurrah!
