Corrupt Twain core fies in Windows XP

  WHogarth 11:49 27 Jun 2005

I have been advised that a recent problem with my scanner may be due to corrupt Twain core files in Windows XP which requires me to reinstall my Operating System! Is this advice correct and does it need a full reinstall? I have also been advised not to reinstall if there is concern over a third party device - my scanner is my only Twain user. Catch 22?

Repair XP by replacing corrupt files

sfc /scannow

in the run box, press enter and let system file checker find and replace missing / corrupt file in windows and explorer.This will take awhile to complete and you may be asked for the CD to be in the drive if windows is not preinstalled on the hard drive.

Repair XP by install over the top of existing systm

1. Boot the computer using the XP CD. You may need to change the boot order in the system BIOS so the CD boots before the hard drive. Check your system documentation for steps to access the BIOS and change the boot order.

2. When you see the "Welcome To Setup" screen, you will see This portion of the Setup program prepares Microsoft Windows XP to run on your computer:

To setup Windows XP now, press ENTER.

To repair a Windows XP installation using Recovery Console, press R.

To quit Setup without installing Windows XP, press F3.

3. Press Enter to start the Windows Setup.

To setup Windows XP now and Repair Install , press ENTER.

DO NOT choose "To repair a Windows XP installation using the Recovery Console, press R", (you Do Not want to load Recovery Console).

4. Accept the License Agreement and Windows will search for existing Windows installations.

5. Select the XP installation you want to repair from the list and press R to start the repair.

6. Setup will copy the necessary files to the hard drive and reboot.

Do not press any key to boot from CD when the message appears.

Setup will continue as if it were doing a clean install, but your applications and settings will remain intact.

Many thanks to Fruit Bat for the suggestions - have tried the 'system file checker' -it took a while to complete, but there does not seem to be any indication of which files were repaired. Have now uninstalled all software associated with scanner using info from 'How do I uninstall twain driver' and when my scanner returns from servicing will start again! Will report then.

My Scanner has been replaced by the Canon Service Dept. - within 5 days - have reinstalled all Scanner software and all features have been tested over the past week with 100% success. Many Thanks for advice.

That's exactly the top notch type of customer service I would expect from Canon.
