The error occurs when I'm trying to create ADO.NET Entity Data Model. The error says:
The preinstalled packages have a reference to a missing Registry value. Could not find a Registry key with name 'EntityFrameworkVisualStudio14Tools' under 'SOFTWARE\NuGet\Repositoty'.
I'm using Windows 10, Visual Studio 2015, and tried to install Entity Framework 6.1.3
I wasted a whole weekend on this issue. I ended up resolving it by going into the registry under \HKEY_CURRENT_USER\Software\NuGet\Repository and made a new key titled EntityFrameworkVisualStudio14Tools and set the data value to 1. Hope this keeps other people from wasting a bunch of time like I did.
The preinstalled packages have a reference to a missing Registry value. Could not find a Registry key with name 'EntityFrameworkVisualStudio15Tools' under 'SOFTWARE\NuGet\Repositoty'.
I had this problem, I solved using this way:
2 - Install it again and choose the packged for your framework ( Individual Componentes )
3 - I havent try it but you can try to install only the individual components for your framework.
I used the second option and it worked with me.
