rustup default nightly fails on windows

[iCrawl]

It seems like rustup default nightly simply won't install correctly on my windows system? I tried searching for any issues about it, but none of them mentioned the same error I am experiencing.

If it's my mistake, I'm very sorry but for now I can't seem to find out why its not normalizing paths (that's what it looks like to me at least).

Running the usual Windows 10 Creators Update in Powershell.

Looks like a duplicate of #1092

I read that, but I wasn't too sure about it, if it is a collab/owner can feel free to close this.
