With the number of people coming to the Discord server complaining things don't work, just for us to find they've installed GTAC into a game's root, I think, if possible, the installer should have a message such as the below in the directory selection screen:

Do not change this unless you know what you're doing.
Do NOT install Grand Theft Auto Connected inside any game directory!

Better yet if possible, could the installer detect the directory path, and flag a warning if it sees any game's name within that path?
