Is it possible to check if a game is run with admin privileges (and if so, request them?)
I can't find anything in OS or Engine.
No. Engine runs on different level than OS. Checking or asking for admin privileges will require some Windows account stuff put inside core and I'm most certain it will break multi platform side of engine. If you want to read/write something runtime you should use res://path to access resources folder or user://path to access user folder (usually somewhere in documents or appdata folder). But res://path is writable only from editor. Use user://path on build, this is why we have it.
Please refer to this page for details about file system.
Have luck with your project.
Garrom out.
