This is not complete by any means but it should be enough to get you started.
No serial number or license server is configured and only the barest minimum is installed so its only realy useful for a render node and even then you still have to get the service configured (user to run as, network share available) and started.
The update to 7.5 can only be downloaded if you have a subscription and you have to unpack it
