Hi again. Now I’m having trouble to download the OpenSpecFun artifact. It happens when adding a package from a custom registry, please see the screenshot attached with the traceback (the user claims they’re unable to copy/paste from the julia console?)

(Original message 
) (More Info)
I have to mention this happened on windows 7 with powershell 2.0 and .NET < 4.5
We were getting the following traceback after Pkg.add("Anything")
Downloading artifact: OpenBLAS32

Stacktrace:
The solution was to install .NET 4.5 and Powershell > 3. This is mentioned in the platform specific instructions but I managed to miss it.
