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

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'm running win7.

    Deleting this:

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

    simply solved the problem!

    Please give it a try. quite harmless to delete anyway.

    Paul,

    I didn't try to move the file to another computer so I just did. I tried to copy the file to my wife's Win 7 32 Bit computer and the file seemed to stay intact. She doesn't have the scanner software installed so I couldn't test to see if it would foo-bar it. I tried to open the file on her machine and it behaved the same as on my computer (Win 7 64 Bit) in that nothing happens.

    Regarding my upgrade. I initally did an upgrade from Vista 32 to Win 7 32 and had problems with the scanner. I then wipped the hardrive, repartitioned it, and did a clean install of Win 7 64. The problems reappeared a few weeks latter.

    Since the last occurance of the problem on Feb 2nd or 3rd the offending file has not reapeared. Still no idea what causes it to show up or how to manually create a shortcut in the Network Shortcuts folder as some posters have mentioned doing.

    I still have a copy of the bad file if you want me to mail it to you?

    Thanks for investigating,

    David

    Darrell,

    I think I had the same issue with the UAC. The Canon tech support guy had me delete my driver and uninstall the software. We then made sure I installed the Win 7 64 BIT version of the drivers and software. That cured that problem.
