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?)

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")`

```julia

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.
