This took me a while to figure out and thank to some blog posts I got there.
The DevCon command-line utility comes in 32bit and 64bit and does the job nicely.
Copy the tool form the link above , extract it to a directory ont teh local machine.
Using the cmd windows , navigate to the folder above and execute the follwing command:
devcon.exe install %windir%\inf\netloop.inf *msloop
press <ENTER>
The following should appear in the cmd window
Device node created. Install is complete when drivers are updated...
Updating drivers for *msloop from C:\Windows\inf\netloop.inf.
Drivers updated successfully.
You now have a Loopback Adpater installed and all that is lect to is create static IPs on both the host and client and you are good to go.
Good Luck
