Canon MP Navigator Stopped working with scanner. Worked under Vista, not Win 7.

Anonymous

Canon scanner Lide 200 worked fine in Vista 64. I upgraded to Win 7 64 and the interface software stopped working - "MP Navigator EX has stopped working". It is a BEX error, Fault module MSONSEXT.DLL_unloaded. I uninstalled, downloaded the newest and reinstalled, same problem. Canon had me create a new profile, program works in that profile. Canon says it is a rights or OS issue.

The scanner works with other software. MP Navigator is a resident program to do copies or copy and email, etc.

Here is the detail from the windows error

I have had the same problem with Win 7 64. I spoke to Canon Tech Support and after an hour during which we tested various things I was told the the problem was with Windows and I should contact Microsoft. I tried creating a new profile which fixed the problem for about a week, then it came back again! The issue may be associated with Windows Update but I am not sure. On this last go around I created a new profile, then copied in the folders and files from the corrupted profile one at a time to see when the problem would start again. After carefully copying files, backing up, testing Mp Navigator, and if necessary restoring the last good setup I discoved that the following file was causing the problem:

C:\Users<user name>\App Data\Roaming\Microsoft\Windows\Network Shortcuts\My Web Sites on MSN

Note: This file was not present in my new profile. Also, the icon has the shortcut marker on it, but explorer says it is a folder. There is no file extension.

I eventually copied ALL of the other data from the bad profile to the new one and MP Navigator still worked! I then deleted the offending file from the bad profile and MP Navigator started working there too!

I then reconfigured all of my software and started IE etc. for the first time while watching the Network Shortcuts folder. The offending file has not reappeared yet. I made a shortcut to this location so I can keep an eye on it to see when it appears again.

Hopefully someone at CANON or Microsoft will fix this "corrupted" profile issue.

Sincerely,

David Witteried

Hey GregDaro,

Thanks for posting in Microsoft answers!

The issue could be related to a corrupt user profile, since you’ve stated in your post that the program works fine in the other profile you’ve created.

Refer the link below for more details on fixing a corrupt user profile:

Hope this helps!

I just went to the Canon forum and found the only thing that worked (and I tried almost everything suggested on this forum): Here is the solution that worked for me (copied and pasted from the forum). I didn't have the PIXMA folder, but I had CNQ9602, which is my Canon folder, and wiatwain.ds. The extra file I moved to the desktop was called sdc330Twain.ds. After I moved it to the desktop, I was able to use my CanoScan 9000F:

Hi jealkon,

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.

I didn't have the Network Shortcuts folder in my Profile, but I had it in my Guest Profile, so I deleted it, but still the same problem with my CanoScan 9000F. I bought the CanoScan 5000F for work two years ago, and it still works beautifully with Windows 7, which is why I bought the newer version for home. Mine worked beautifully, too, until about a year ago. I can scan photos from Paint but not from the Navigator. This would be okay except that Paint doesn't divide multiple photos into individual photos. Any other ideas out there? The Canon techie couldn't help me either--said it was a Microsoft issue.

Dumb, yes but it works. Don't know if Canon, Microsoft or SMART Notebook makers is responsible for the incompatibility.

This turned out to be my problem as well. To whom would we report this? It's a pretty major issue for many of us.
