title: Can't install nuget package because of "Failed to initialize the PowerShell host"
body: <p>All of a sudden, I am getting this error when upgrading Nuget packages.  None of the fixes that I have come across work.  I am using Visual Studio 2013.</p>

    <p>Attempting to perform the InitializeDefaultDrives operation on the 'FileSystem' provider failed.</p>
