Calling it now, you've gotta be magic.
There's no real way to actually know if win8 changes anything when i don't use it - but people seem to have immense trouble installing on it for whatever reason, so I can only assume, seeing as a ton of other older games apparently run weirdly on it.
Most people's problems seem to somehow relate to broken/incomplete file downloads though with missing stuff, which I still don't quite understand if they're downloading from getuploader. It's hard to figure out what's going wrong when you've installed it all with no trouble. :/
