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!

    THANK YOU SO MUCH for posting this. I have had the same nagging problem when I switched to Windows7 64 bit, and thought it was bad drivers

    or software. After downloading and updating everything it STILL didnt work. But when I saw your post, I created a user account simply named SCANNER.

    So when I want to scan, I just SWITCH USERS and scan my little heart out...... I love it when I find answers from other guys like myself here.

    This was the  key for me.

    Jdossey,

    Have you tried deleting the following file in you "broken" profile? I discoved that the following file was causing the problem:

    *C:\Users<user name>\App Data\Roaming\Microsoft\Windows\Network Shortcuts*

    Delet the file called: "My Web Sites on MSN"

    Oh yes, I forgot that another user had to delete some other shortcuts in the same location to get his scanner to work. Here is what he posted:

    "Very cool - this worked for me too!!!  Well, not exactly the same but almost.  I had two other shortcuts in the same folder and I needed to delete both of them to get MP Navigator to start but that did fix it!!!  Thanks a lot - good detective work!"

    Substitute your user name as indicated above. Delete the file(s) and try your scanner, it will probably work. I have seen this file reappear in the past but haven't been troubled by it since last February.

    NOTE: I tried moving the offending file to various places on my system and it caused problems no matter where it was located, except the wast basket.

    You might need to change your folder settings to show hidden files and folders to access the location. You can do this by opening the file manager, pressing the Alt key, then selecting the Tools-Folder Options menu. Select the View tab and enable the Show Hidden Files, Folder and Drives option.

    I am still amazed that Canon and Microsoft haven't corrected this yet.

    David

    David,

    Like all the others I had the same problem with my MP620: I could print via wireless but not scan in W7 32bit.

    Our XP and Vista computers in the same network can print and scan via wireless.

    I tried everything all of you have advised and nothing helped.

    I then searched the Canon website and found mp620swinns103ea24.exe (MP Drivers for Network (32bit)) (64 bit is also available.)

    I started this program and now everything runs perfect.

    This exe file is special for the MP620 but maybe also traceble for your printer model.

    Hope you can have profit with this message.

    Rob
