ERROR: The class installer has denied the request to install or upgrade this device Verifying if the W32.Klez.H@mm Exist on the Computer

  1. Search the system for the file wink*.exe.

  2. If the search finds any executable files beginning with  wink , then this is an indication that the computer is infected with a WORM_KLEZ variant virus.

  3. For resolution, refer to one of the following URLs for information on how to remove the virus from the computer.

Symantec website
http://securityresponse.symantec.com/avcenter/venc/data/w32.klez.h@mm.html
Trend Micro website
http://www.trendmicro.com/vinfo/virusencyclo/default5.asp?VName=WORM_KLEZ.H

Important - Once the virus has been removed from the computer, it is necessary to reinstall the device driver.

I bought a new com. and now I can't find my instal. cd for my Canon Scanner D646Uex. Is there a way to obtain one please?


I have many years experience repairing Canon scanners so here is my suggestion for you.

You can contact Canon directly and Im sure they will be happy to sell you one. Or if you just need to get the scanner back up and running again here is what I would do. Just google Canon CanoScan D646U drivers. A page should come up that takes you to the official Canon website. Download the latest drivers for your scanner they are free. While your there download Capture Perfect its software you can use for scanning and its free too. Make sure your scanner cable is unplugged from your computer install the new drivers and rehook up the cable with the scanner powered on. A window should pop up saying a new device or drivers are being installed. Once that completes reboot(restart) your computer and you should be good to scan now.

I hope this helps you out.

I run windows 7, but I cannot get the driver for my scanner - Canoscan D646u ex (yes, i know, its a dinosaur -- but its not broken)


Unfortunately , the production of drivers stops at W XP .
If you have the W XP install disc , you can install a virtual version of W XP on your machine from http://www.vmware.com/products/player/
If you still have the install disc , you can also partition your primary and install W XP on the new partition from http://download.cnet.com/Partition-Wizard-Home-Edition/3000-2094_4-10962200.html. Easy and safe , no specific knowledge required .

Installed the driver showing in device manager but not in my computer


Hi!
Try installing the driver for the scanner again or when the scanner is connected a new device connected toolbar will come out hen just follow it up until installation will proceed. Try opening your my computer in the start page and see if the new driver was installed.

connect all cables and power it on before turning on the pc so that it will be detected.

After installing the driver and trying to use the scanner, I get an error from the new hardware wizard. The error is "the class installer has denied the request to install or upgrade this device" I am...


This error may be due to other devices that detects on your computer, it may be a device of mother board hence I suggest you to check device manager for any yellow question mark and then install the driver accordingly.

Driver download


Dear Sami Kotaich,

unfortunately your Cannon has not released drivers for vista for this product.

I can give you one suggestion; connect your scanner with vista PC and atleast let it try to install necessary USB drivers. once it has been done you will see message your hardware installed or there was a problem installing drivers for your hardware and it may not work properly.

now leave scanner connected and go in start menu- programs- accessories- paint

once you are in paint click on File Menu then From Scanners or Cameras. if it does recognize and you get scan wizard then you will be able to use your scanner on vista. but if it doesn't recognize then I am sorry you might need to get more authentic recommendation from Cannon support.

let me know does it work or not? or if any more questions, please do not hesitate to contact me.

Many Thanks.

AJoshi
