VS2013 Cant Install almost anything through NUget (specially requiring entityframework)

I can't install Entity Framework via Nuget on Visual Studio 2013 Ultimate.

I've tried:

• reinstalling it
• update it (vs2013) patch5
• .net frameworks fixer (FixDotNet2017.cab)
• other nugets versions
• EFTools6.1.3ForVS2013.msi
• msxml6_SDK.msi
• repairing w/ MSXML
• dotNetFx45_Full_setup.exe

I've wasted a whole week on this - but in the same PC another VS 2017 works fine..

Here are the outputs:

ENTITYFRAMEWORK Install failed. Rolling back...

Installing 'EntityFramework 6.1.3'.
Successfully installed 'EntityFramework 6.1.3'.
Adding 'EntityFramework 6.1.3' to WebApplication5.
Uninstalling 'EntityFramework 6.1.3'.
Successfully uninstalled 'EntityFramework 6.1.3'.
*Install failed. Rolling back...*

    + CategoryInfo          : NotSpecified: (:) [Install-Package], InvalidOperationException

What I really need to DO is add a new item to my solution , an ADO.NET ENTITY DATA MODEL

and the error follows like: library not registered Exception from HRESULT: 0x8002801D (TYPE_E_LIBNOTREGISTERED))
