Missing registry Key for Intel I211-AT LAN

Hello,

I need some help, think I messed up something.
The modded driver package by Canonkong for AMD chipsets works flawlessly, I was able to run Win7 with B550, X570 and X399 without problems just swapping the motherboard, no reinstallation needed.
I know it is not optimal to do so, but still it is ok for me.

The problem is, I temporary swapped a B550 for a 1155 motherboard.
For reasons unknown I decided to uninstall all intel LAN programs and software.

I swapped again for a X399, all good BUT…
The Intel I211At won’t install anymore, no matter whuch driver package I use, it is recogognized but the installation won’t complete because “the system is unable to find the related registry key for the peripheral”.
I think I cancelled somehow crucial registry keys that allow the modded lan drivers to work.

Was not able to find anything on the web, probably it is just me and my stupidity.
Does anyone know Win7 enough to know which registry key I need?

Thanks
