Help with installation on Windows

An incomprehensible error comes out during installation (there is memory, the Internet is stable, antivirus is disabled).

It's hard to tell from the screenshot so does it stall indefinitely or is there an error message when it finishes?

It looks like it's getting stuck renaming a directory (presumably because something has a handle open on it) so it's possible it may resolve itself.

EDIT: It might be this issue: https://github.com/rust-lang/rustup.rs/issues/1912

The advice there is to try setting RUSTUP_IO_THREADS=disabled.
