Does anyone know how to fix this problem?
The system extension CNQL2410_ClassicNotSeize.kext was installed improperly.
I'm not sure what is triggering the error.

It's happening on my Mac too, I think it's something to do with the Canon Scan Gear software and a PowerPC component that won't run because the default installation of Snow Leopard doesn't include Rosetta?
I haven't tried this yet but either install Rosetta (a dialogue will ask you to do this is you launch a PPC app) or see if you can find a Snow Leopard compatible scanner driver on the Canon site.
fwiw, i just got the same error message while installing an updated Line6 driver and i do have Rosetta installed. i do also have a CanoScan LIDE scanner and what little turns up on Google suggests that this may the source of the problem. why installing a Line6 driver triggered for me, though, i do not know. possibly a freakish coincidence.
the same message appears after the installation of Vodafone Mobile Broadband 3.04.06.00 GMC on my MacBook (and it don't work with Snow Leopard ...) adriano p.s. I also have a Canoscan LIDE 500 F p.p.s. installing the old Vodafone Mobile Connect I obtained 5 (!!!) Kernel panic ... so, do you know if exists an universal drive for Huawei E272 ?
Sounds like a Canon issue. I too have the CanoScan LIDE 500F and Snow Leopard – however I didn't have any problems installing Snow Leopard, but just now I installed iTunes 9 and got two errors; "System extension can not be used" for both /System/Library/Extensions/CNQL2410_ClassicNotSeize.kext and /System/Library/Extensions/XEROX USB Printing.kext
I got the same error in installing Xcode from the Snow Leopard CD. No problem reported when i upgraded the OS to 10.6, and am running Rosetta.
Also have CanoScan LiDE driver and CanoScan tools installed. They've never worked well; however, Image Capture does work well with my model (500F) and has all the features i was able to access with the Canon tools before Snow Leopard.
