Hi!
I have an issue with installation rustup.
I've tried to install rustup, but received some error messages.

I've tried via CMD, PowerShell, mingw.

PC Environment
Windows 7
proxy exists,
not trusted certificate. (need to disable SSL verify)

I also tried to register cert as follows, got same error.
#581

thanks for reading!

The situation has been occured in the office, which has proxy and self-trusted certificate.
I think that certificate is a problem.
I need to know the way avoiding ssl-verify in rustup installer.
like avoiding ssl-verify in git as follows

git config http.sslVerify false

The problem solved. I installed rustup with RUSTUP_USE_REQWEST variable.

# mingw bash
RUSTUP_USE_REQWEST=1 && rustup.sh
