Hi there! Sorry for the late reply, and hmmm I honestly have no idea why you had this error message; I have had a few other people playing my game and they all launched normally. I'm sorry to say that I can't really help you with it because I know absolutely nothing about software, codding and all that wizardry. Personally I use Winrar to extract RPG maker games and MV doesn't need any runtime package to play hmmm...
