Games on the RPG Maker engine require the installation of RTP packages.
What kind of package is needed for the game?
This is indicated in the header of the distribution of the game. Different games may require a specific package. It all depends on the developer and on what kind of RPG Maker engine he made this game.
If there is no mention of the required RPG RTP in the design, then look in the "readme" file of the game or in the ini file. The easiest method is to install all the packages and forget about them.
