MP Navigator EX 4.0 stopped working

[bob12345]

Hello,

When I try to open MP Navigator EX 4.0 for a Canon LIDE110 scanner, I get several dll issues.  mpnplib.dll either not designed to run on Windows or it contains an error.  Same message for mpnfimp.dll and mpnscmgr.dll

The program was running before but would not open today.  Tried re-installing and updating drivers but still getting the same issue.  

I am running Windows 10.  

Can anyone help?

Hi bob12345,

You can try completely uninstalling the scanner drivers and MP Navigator software from your computer, then restarting it and reinstalling the drivers and MP Navigator software again to see if this will resolve the issue.  When reinstalling the drivers and software, if you have any antivirus, firewall or anti-spyware programs installed on your computer, please temporarily disable them prior to reinstalling, as these programs can sometimes prevent the successful installation of the drivers/software.  Once all items are installed successfully, you can re-enable the protection software. 

Should you still experience difficulty, we ask that you please contact a Canon technical support representative here for further assistance.  A representative will be happy to assist you free of charge.
