That's why you don't say "check my signature" but always post links, because years later your signature can change
And it's not the "wrong version of RPGM" it's because you don't have the RTP
RTP are a bunch of file common to all RPGM games so once you DL it one time you have it for all the game requiring it
It allow devs to reduce total size of their game by using assets that are already on your computer in the RTP so no need to include them each time in each game
Go here :
You must be registered to see the links
Download the right RTP that correspond to the RPG Maker version of the game you try to play
In this case, this game was made with RPG Maker XP, so you need the XP RTP
Install it and that's it you can play, and you can also play all other RPG Maker XP game that need the XP RTP to run
And if you wanna be sure to never run into this problem again, also download and install the other RTP for all the other version of RPGM
Just install the "XP", "VX" and "VX Ace" version, that's probably the 3 you ever going to need, I've never seen once a RPGM 2000 or 2003 game, and even , good luck to make it run on a modern windows
And the 2 last version of RPGM , "MV" and "MZ" don't need any RTP
