Symbolic links on Windows

[bkamins]

This is speculative as I am not an expert here.

On my Win10 unpack fails because creation of symbolic links throws an error that is not caught.
Maybe on Win10 ENV["BINARYPROVIDER_COPYDEREF"] should be set to "true" by default on this platform as this solves the problem.

I am not sure if this is my local problem or a general problem for Win10.

I'm seeing a different but related issues on Win10. In particular, when using the package (inside https://github.com/QuantEcon/InstantiateFromURL.jl), we initially get some Warning: Creating symbolic links on Windows requires administrator privileges. Nothing seems to break because of it, but it would be great if we could either fix or disable it, if only so that people don't worry.

Yep I see this too

Is there any way to swallow or turn off the warnings when including the package?

(Note on the above, we've tried @suppress and friends from Suppressor.jl, but no luck)

This is related to #149, I filed PR #165 to suppress the message.
In order to troubleshout @bkamins issue, we would probably need an error log...
Maybe the issue is meanwhile solved?

I do not run into this issue as it can be worked around on Win10 by running Julia in administrator mode.

@pszufe - do you remember installing which package on normal user mode triggers this error?

[hhaensel]

I think this is now solved with #166

[bkamins]

I will reopen the issue if I encounter this problem again.
