Okay, so I've spent a while reading about this. Windows has no understanding of something called "executable bits", but this is something both Linux and MacOS use. It is impossible to add this on windows. So, I needed to emulate either a MacOS or Linux Terminal to add these executable bits.
As far as I know, there is no reliable Mac terminal emulator for windows, so I used Linux. Anyway, I jumped through a lot of hoops, and I feel like it may have just completely broke the build, but I did put a new one up; hopefully this works.
Please let me know, so I can try again if it's still not right
