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!

    Hi Joe,

    I think you have the solution for at least some of the posters in this thread and did not even realize it.

    I was getting frustrated, because I've been searching everywhere on the Web to find a solution with no success. I tried David's solution of first creating a new user profile.  I was not able to get the MP Navigator to work under the new user profile.  So, it was quite clear that the problem I was having was not a profile issue. 

    I also had no entries whatsoever under "C:\Users<user name>\App Data\Roaming\Microsoft\Windows\Network Shortcuts" such as "My Web Sites on MSN". And yes, I did have explorer set to show hidden files. I'm happy that David's solution at least worked for some people.

    So I stumbled upon your comment "Then the guy said go to the TWAIN_32 folder and remove anything that is not a Canon folder or the file wiatwain.ds".

    I tried this and it worked for me.

    Here is what I did:

    Go to "C:\Windows\twain_32"

    Cut and Paste:

    Cut all files except the following: Canon files and folders, wiatwain.ds (In my case I was left with two folders: MX870 series, MX870 series_001E8FEE33BF, and one file: wiatwain.ds)

    Paste all files except the Canon files and folders, wiatwain.ds, into a temporary directory

    Now try MP Navigator. If it works, then it appears that the Canon twain drivers are conflicting with the other drivers in the Twain_32 folder.

    You can now paste the other files one-at-a-time back into the Twain_32 folder each time checking to see if MP Navigator is still working.  The moment it stops working, you know what file was causing the conflict.  In my case, it was a file "SilverFast (UScan-SE).ds" which is a file from SilverFast scanning software I had installed on my computer.

    I hope this helps some of you!

    Cheers,

    Bill

    Colon, thank you sooo much for YOUR post. Originally I had created a new user profile called "Scanner" just for the purpose of using the scanner. But when I read your post, I went in and found this folder called "Network Shortcuts" and it ONLY contained 1 shortcut "My Web Sites". I deleted that and now my scanner works perfectly on my administrator user profile like it did in Vista. It is GREAT. This Forum has helped me find a lot of things. Happy Holidays to everyone.

    Wow, this is great, it has solved (not resolved) the issue of my Canon scanner.

    I recently purchased new laptop running Windows 7 Home Premium 64 bit and installed my Canon LIDE700F scanner software and it did work. But then a month later it stopped working. Did all the usually, go to Canon site, uninstalled, installed, updated etc. Then I saw this forum and noted that I had shortcut files including the My Web Sites on MSN.

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

    I deleted that, and it still did not work, but then I deleted the other 3 shortcuts in the same Network Shortcuts folder and now my scanner works. Thanks to all for this solution, as you just get the run around with Canon and Microsoft. Hopefully someone at CANON or Microsoft will fix this "corrupted" profile issue.

    Colin
