Solved How to reinstall NIHostIntegrationAgent?

I am trying to re-install NIHostIntegrationAgent, and so I tried uninstalling Komplete Kontrol, Controller Editor, and doing that did not remove NIHostIntegrationAgent.

So I ran the windows command "sc uninstall NIHostIntegrationAgent" which removes the WIndows Service completely. Now, no matter how many times I completely uninstall/reinstall Komplete Kontrol, Controller Editor, they won't work. I even downloaded the S88MK driver from the NI Website, uninstalled/reinstalled, to no avail.

What installer is actually responsible for installing the NI services? How can I completely remove them and reinstall them?

 

I think I figured it out -- I renamed the following directory to Hardware_Old

C:\Program Files\Common Files\Native Instruments\Hardware

Then, ran the "NI Uninstall RegTool_64bit.exe" utility and selected "NIHostIntegrationAgent"

Then I ran the Komple Kontrol installer again, and that seemed to recreate the C:\Program Files\Common Files\Native Instruments\Hardware directory and reinstall the services

 

NIHostIntegrationAgent is a part of the Komplete Kontrol drivers. You can uninstall it using its own entry on the Windows 10 settings.

 

This is it!! This is what made my NI keyboards come alive after all these months. Thank you!
