Need file cnmnpu.exe

[Bluestater]

I need a link to this file: cnmnpu.exe. Please do NOT tell me to look on installation disk. Obvioulsy if I had it I wouldn't be asking the question. 

[Bluestater]

I have a CNMNPUT.exe but it is inoperable. Date created 8/30/12.

Did you try what Patrick provided?

[Bluestater]

Yes. Does not work. See post directly above yours.

Do not move the file outside of the folder that it is in before running it.

[Bluestater]

Thank you. Found it. 

Please leave this up. There are other people who need this solution as I saw many posts about the same subject.

I too need this file, or at least a solution for my MF644cdw.  When I try to run the driver installation software from the optical disk it fails because it cannot create a port.  Best solution I can find from others with the same problem is to run this file to remove printer ports.  This is a refurbished computer and may have had other printers installed in the past.

This is extremely frustrating that I cannot use my $400 laser printer because of a basic software conflict.  I really thought the Canon software would be written well enough to fix this issue itself.  Please help.
