I tried rustup on windows and I get the 32 bit binaries (nightly-i686-pc-windows-gnu) even though my PC is 64 bit. Is this a known issus?
Later edit:
I noticed rustup-init.exe is 32 bit also.
Another more severe issue is that rustup.exe process seem to be hanging and it cannot be killed from the Windows Task Manager. Due to this issue, I cannot remove the .cargo and .multirust directories and I have to_force_ reboote the PC to recover (using the power button).
