Installing EntityFramework 6.1.3

I am getting the following error when installing Entity Framework with Visual Studio 2015 Community Edition:

I have tried bricelam's solution here, but neither replacing the psm1 file nor copy-pasting the text works, and produces the following:

Import-Module : File \\Mac\Home\Documents\Visual Studio 2015\Projects\Vidly\packages\EntityFramework.6.1.3\tools\EntityFramework.psm1 cannot be loaded. The file \Mac\Home\Documents\Visual St udio 2015\Projects\Vidly\packages\EntityFramework.6.1.3\tools\EntityFramework.psm1 is not digitally signed. The script will not execute on the system. Please see "get-help about_signing" for more details..

This is all in an effort to run enable-migrations, which, naturally, failed.

If it matters, I am running Windows 7 x64 using Parallels on a MacBook Pro.

EDIT Mark Sowul's answer below points to the fact that using a network share, a Parallel's feature, would cause this issue. I am unsure how to change the directory, however.

You're running against a network share (\\mac). Try running it against a local directory. As part of the nuget package installation, it is trying to run a powershell script. For security reasons, by default, remote scripts across the network will not be executed.

Note that stackoverflow is escaping the double-slash in the original post, and I had to put in four slashes to get it to show up properly here.
