Fresh install Julia 1.6.0-rc2 on Windows, error trying to add a package

[sairus7]

If I open Julia 1.6 console without admin privileges, I get the following error when trying to install a package.
(With admin it installs with no errors.)

@musm, any ideas?

[sairus7]

Maybe that's because I have changed install path for Julia to C:\Julia\1.6.0-rc2? Maybe there are some relative paths involved? (I am looking to strange path C:\buildbot\worker\... that doesn't exist on my machine.)
Or because I have 1.5 already installed?

[musm]

I can't reproduce. For reference I also installed Julia to C:\Julia to try and reproduce this.

[giordano]

The fact is that installation of artifacts swallows all errors: JuliaLang/Pkg.jl#1659.

Unless you find out what's the actual error, there is nothing that can be done. DebugArtifacts.jl tries to replicate installation steps in a more verbose way

[anandijain]

I installed Windows 1.6.0rc2 with run as admin but then ran julia without admin. This might be how to repro

[musm]

Oh that would be the issue. No need to install as Admin, even in a non-standard directory.

[anandijain]

sure... there is a note during installer roughly saying "if you want to install everywhere, rerun installer with admin", so I did

Looking at the bame for the place that throws, I will guess #39491 is the cause of this. Specifically in

julia/base/file.jl

Line 1042 in 4b6b9fe

if !(flags & UV_FS_SYMLINK_JUNCTION) && err == UV__EPERM

it looks like the first condition is an Int.
