Windows Defender Install Sufficient Privileges
I know it's a bit later on but I found a way to get this working on the Windows Server (2012 R2) that I was having the exact same issue with.
It seemed to throw this error due to the service "WinDefender" being installed.
For me I tried to install the md4ws.msi from the get go but got an error so went back and installed a bunch of updates, then ran into the above error.
After trying again and again eventually I found the above mentioned "WinDefender" service that had a broken description, leading me to believe this was the problem.
I removed this service by deleting it from the registry, this was done by deleting the reg key "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControl\Services\WinDefender" and then restarting.
Once the server came back up, I ran the installed via an admin command prompt and bingo! It installed successfully. I could then carry on with the onboarding process.
I hope this helps and works for you! (and others).
