Windows 10 MG3620 installation fails - "New port could not be created: 0000"

[jemmer]

I'm trying to install a Canon MG3620 on my Windows 10 network.  I was able to install it via my laptop on my wireless network and that works fine.  I'm trying to do the same on my desktop via a wired connection to the same network (same range of IP addresses).  During the installation process the printer is correctly detected, but during the install WP drivers portion, this fails with the "New port could not be created: 0000" error.  Retrying does no good.  Trying via the administrator account gives the same error. Turning off Defender and the Firewall gives the same error,  Rebooting does no good.

Thing is, once upon a time this worked just fine, but I had to temporarily move the printer to another network in another location where all devices were wireless.  After some fiddling, I got all devices to recognize and use the printer there.  But, when I brought the printer back home, I was only able to get the printer working by using my wireless laptop.  My wred desktop gives the port could not be created error.

Can anyone help?  This is driving me nuts...

Thanks

All computers involved in this are running Windows 10.

I thought my original post described the situation pretty well.  If anyione has any additional questions, I'd be happy to answer them.

OK.  I managed to find a solution.  A Google search uncovered a suggestion to try the program CNMNPU.EXE located on the installation disk.  This apparently deletes the ports that the Canon install creates.  The theory is that previous installations leave one or more ports around, and a new installation fails trying to create a port that already exists.  This program deletes the Canon port(s).

I was able to install the Canon software and drivers by first running the CNMNPU.EXE program, then insuring that all Canon printer software, including the MP drivers, is uninstalled, then rebooting, then retrying the installation.

To my delight, the install worked, and all appears well.

YMMV.

This appears to me like a bug in the Canon installation procedure.  It shouldn't fail if a port it is trying to create already exists.  But at least there is a workaround.

Thanks for your posting, Jemmer; I had the same issue with my model no. Mx340. Here's what I did:

1. I found the "CNMNPU.EXE" file on my installation disk (<Your drive letter>:/win/Driver/LAN folder), and I right-clicked on it and chose "run as administrator." When it completed, I restarted my computer.

2. I reran the "mp68-win-mx340-1_06-ea24.exe" file─also as administrator. (This is the MP Navigator driver installation file for my printer from Canon's website.)

That's it─no need to uninstall the software beforehand.

I did a lot of searching before finding your posting. I really appreciate it when people return to forums and post the solution they've discovered for their computer issues. Thanks again.

I am having the same problem on an older Pixma 6120  My installation disk does not contain a file by the name suggested here.  Am I doing something wrong?  Your help is appreciated.

Thank you so much for this! I copied the whole LAN folder from my disk onto a thumb drive (since my new laptop doesn't have a CD drive) and ran the CNMNPU file from it. Totally worked.
