There's no install package, at the moment.
Mostly because I thought that, for an inexperienced user, the most difficult thing would be actually using TrID anyway (being a command line tool), and so an easy to install package wouldn't have helped much.
But it still something I may consider.
Mostly, I would like to publish some kind of super easy to use complete package, with an easy to use GUI, ability to search, filter by file types, rename, etc. Will see.
