What OS are you using specifically? Officially, RPGMaker MV goes as low as Windows 7 32 bit: https://rpgmakerofficial.com/product/MV_Help/page/01_01_02.html. RPGMAKER MV is not officially compatible with XP, and is known to throw this error when attempting to run on that OS ("game.exe" and "an rpg" almost certainly means the OP was trying to run RPGMaker). RPGMaker games are actually just a webpage with a javascript blob, being run in a headerless browser, so with some security tweaks you can just drag the index.htm file into a browser and it will...kind of work, though it may be laggy and have plugin bugs. However, if you're running XP, whatever browser you're running is probably too old to handle the stuff RPGMaker is trying to do either.
RPGMaker MV is VERY forgiving and backwards compatible, Windows 7 came out in 2009, but there is a limit to how far back we can go. If you ARE on XP, I highly recommend an upgrade: thriftstore pcs, or mass-dump corpo systems like the dell optiplexes on ebay can be picked up for $100 or less and run Windows 10 just fine. Let me know with more details though.
Also, for future reference, if you need to share an image, here or elsewhere, use catbox.
