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!

George, I would suggest creating a user profile and see if the scanner works when you log in with that account. If it does, then you will know that there is something rotten in your current user profile. The next step I would try if your profile is corrupted is to delete the network shortcuts folder and see if the problem goes away. If not, you can restore the folder or create a new on. I haven't seen anything show up in that folder since I cleaned mine out last spring. Sincerly, David

I am in the same boat as Natalie. Nothing is in my Network Shortcuts folder. I cannot justify the time and risk of creating a new profile and moving files around in a trial and error method. I emailed Canon about this problem today. First they said reinstall all the drivers and MP Navigator. (I had already done that three times.) Then the guy said go to the TWAIN_32 folder and remove anything that is not a Canon folder or the file wiatwain.ds

Of course none of this worked. I really wish Microsoft and Canon would quickly fix problems like this, instead of cramming all sorts of new features into software. This thread has been going on for over a year now, and still there is no real solution. If anyone finds a real solution from Canon, please post an update to this thread!

Thanks,

Joe

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
