Rust windows installer failed when not run with admin privilege

[buckle2000]

Installer: rustup-init.exe

How to reproduce this bug

1. start installer without admin privilege
   Wait for download
   When download of component rustc is completed, the installer says Access denied and halts.

2. start installer with admin privilege
   the download is now complete, but the installer will request byte range of size 0 from the server, results in error Cannot get multi-part....
   .multirust/ must be deleted to correct and restart installation

It seems somewhat related to #1188

As well as deleting .multirust, I had to remove the partial download from .rustup\downloads too.

@ferrouswheel ironically the downloaded file it is not partial but complete. rustup just need to move it to the appropriate place.

I am on Windows 8.1 and rustup-init required admin rights and installs rust in the admin account. Making it un-avaible for my default non-admin user.
So, is there a way to get a clean install without copying the files manually?

EDIT: I see now that even when I changed to gnu it installed msvc...already reported #1409

Do you have CARGO_HOME set to something non-default?

Rustup does not normally require admin privileges to install. Does the error message give any more details than just "access denied"? Do you use any additional security software or have any unusual restrictions?

I just downloaded last version (1.26.1) and could fix this by un-checking the Run this as administrator option in the rust-init properties. By default Windows marks this as admin's right required.
Screenshot in Spanish but I assume the position of the option is the same in other languages.

Clarification: after this, rustup, rustc ... installed in my non-admin user correctly and is working fine. No need to define CARGO_HOME or do anything else.

Zero idea what was going on here, but the download cannot carry the admin-privileges bit, so it must have been something local / windows 8 specific. Please do reopen if this is still happening.
