when i run the game theres a message that say "rpg maker 2003 rtp is not found" and the setup.exe doesnt do anything what can i do
You have to download the RPGM2k3 RTP and install it on your system, or you won't be able to play games that dosen't include it.
You can download it from here: https://www.rpgmakerweb.com/run-time-package
