Hi Rory, sorry for the late response. I've been investigating what the potential issue could be and testing the game on other systems to see if I could replicate it but no dice for now. The only thing I found digging is that potentially that message comes from playing a game built for a 64 bit system using a 32bit system. I Really dont think tha that's case given that your specs are way better that the ones we use to build the game xD anyway I uploaded a x32 version of the game built for those platforms, maybe you can check if you can play that version? Sorry in advance, I really hope this fixes the issue and thank you for letting me know about it!
