Hey Orange!
Sorry you're having issues getting the game up and running.
As llo mentioned, AHITR uses Renpy and everything needed to play is already included. Usually it can take 30-60s for the game to open for the first time.
There also has been known issues if you have any anti-virus software running, it might flag the game as a false threat, making unplayable until you allow it through the program.
Hopefully you manage to dive into AHITR and looking forward to hearing your thoughts!
