Running Windows7, 64 bit Oper System
Scanning was not an issue prior to a few days ago. No new software or programs have been installed.
Went to scan a document and scanning looked like it was working, then it greyed out and received error message: Canon MP Navigator EX has stopped working.
Searched internet for solutions and tried them. Nothing works. I've gone as far to un-install all Canon products and utilities, even went into registry and searched and removed everything I thought I could related to Canon.
Still receive error. What do I do now?
Guess I've pretty much stumped the panal since there's been no response
Solved! Go to Solution.

For testing purposes, please try to temporarily disable any firewall or anti-spyware programs on the computer to see if this will allow the program to run properly.
Also, if you have a different user account on the computer, try using or creating a different account to try and narrow down the cause of the error.

Previously tried each of your suggestions and also tried this again. Stll does not work. I actually tried launching under the other three profiles on my PC and well a creating a new one.

There may be a third party scanner driver interfering with MP navigator. Please try the following:
1. Click 'Start' and then 'Computer'.
2. On the left-hand pane, click the down arrow beside Local Disk (C: ).
3. Click the down arrow beside Windows to open the folder
4. Highlight the twain_32 folder.
5. The folder should have 2 folders that start with PIXMA MX870 and a file called wiatwain.ds. Any other folders or files should be dragged to the desktop.
6. Reboot the computer and try scanning again.

Thanks so much, there was one additional file. SDC330Twain that was int folder. Put that on desktop, rebooted and scanning appears to be working.
Consider yourself a genius because no one has been able to solve the issue

Had this same problem with an Lide 110 scanner and found the same file (sdc330Twain.ds) in C:\windows\twain_32, removing it sorted the problem - Thanks Very Much
Just to add, this file is installed with 'Smart Notebook' which is interactive white board software from Smart Technologies. From the small amount of testing since removing this file, the Smart software still seems to operate as normal, but updating the Smart software reinstalls the sdc330twain.ds file.

I have been using my printer with this computer happily for several years and I have started getting and error meeage:
canon mP navigator Ex stopped working. Only the scanner is effected.
I have tried:
uninstalling the scanner software and then all the printer software.
Looking for hidden files in the network shortcuts: none found
Looking in the SDC330Twain folder for additional files and none were found.
I have rung Canon who advised me to reinstall windows which seems rather extreme and Microsoft.who directed me back to Canon.
