I do have the same question.

Suddenly printer stopped working. Can not uninstall drivers and can not reinstall it as well. During installation system broke up with message ERROR 3: Failed to copy port monitor files.

Did all actions offered via virtual agent with Command Prompt option.

Can anyone help?

Welcome to the HP Support Community! I'd like to help!

I see you are experiencing issues with the HP ENVY 4500 e-All-in-One Printer gets error Failed to copy port monitor files.

Try uninstalling the software using below Fixit utility from Microsoft:

http://aka.ms/Program_Install_and_Uninstall

Also be sure to uninstall any other HP Software existing on your computer, assuming you don't have other HP products

Note: If you have another product or an HP Computer please let me know the exact model and what HP applications are listed under Uninstall a Program and do not proceed following the next steps.

Next, browse to C:\Program Files and delete any listed HP, HP Inc or Hewlett-Packard folder.

Browse to C:\Program Files\Common Files and remove any such folder as well.

Browse to C:\Program Files (x86) Files and remove any such folder as well.

Finally, remove any such folder under C:\Program Files (x86)\Common Files

Now reinstall the HP software and check for any difference.

Hope this helps! Keep me posted.
