Hi! Could you please screenshot and send me your error message please? It'll help me figure out what the issue is. Maybe try downloading from this website instead? https://rpgmaker.net/games/9699 I believe that 'Compatible' issues usually have to do with either 1) your computer possibly being outdated or 2) you aren't using Windows, which is the only system that RPG Maker can work on. Does this error show when you download any other RPG Maker games?
