I'm going to close this as a dupe of #626, sadly our installation on windows currently requires a MinGW installation (and MSYS2 most likely), and the script is kinda lucky to work on Windows even with those installed! We've got a PR to make progress in this direction, so it should be coming soon!

For now, you can just copy out the cargo.exe binary and run that directly, sorry about the trouble!
