Hello, I am not asked to install an application to play the games.
Do you know an application to be able to play them?
the RTP source files can be found o rpgmakers home page and they are free just look for the RTP that you need and download it if the RTP is what you need then after installing you should be able to run the game also i dont know witch engine this game uses so you will have to test your way forward
here ill help you to correct page:
You must be registered to see the links
try downoading and installing any of these there are 2 more rpgmakers programs called MV and MZ i dont know if you need RTP for those but if you do i do not know where to find those because they are not on this pagelink i added.
this is my guess on why you cant run the game alot of developers dont include the source files in thier games and this is why you need the RTP it inclueds files needed to run the game, i hope this solves your problem
edit: i did some scanning on some rpgmaker forums and it turns out MV automaticaly includes the RTP files in game folder when creating a game, im guessing its the same with MZ because both of them dont have a RTP downloads on the homepage, so your problem is something else all i know is that you do not need the RPGMaker MZ or MV programs to run the game. sorry i cant help you
