(7. So that it automatically start every windows startup):
You'd have to check all three boxes related to "service" that is in the bottom part of the "Config Services" tab of LMTOOLS. And then go to services.msc, change the startup type to Automatic, and the Log On user to Local System Account (very important, because the service will fail to start without this).
Follow these steps and you'll be golden. I hope this helps.

for services.msc, go to start menu and search "services". open app and scroll to "Autodesk Desktop App Services"

After opening Autocad, if you get a poppup, just add your "hostname" again.
