If you have this problem installing the VSIX for VS2015 and don’t want to install the online one from the “Extensions and Updates” menu shown above (e.g. because it says version 4.4), or if you want to install the VSIX for VS2013 where the “Extensions and Updates” menu can’t connect to a server at all, I figured out how to force the VSIX file to work.
In my case, I the VSIX Installer for 2013 gave me “Install Failed…This extension is not installable on any currently installed products”. When I clicked on “View Install Log”, it showed that when it searched for Visual Studio versions, it did not find VS2013:

The fix was:
- Run “Developer Command Prompt for VS2013”
- Change directories to the one containing the “netmfvs2013.vsix” file
- Run the command “VSIXInstaller.exe netmfvs2013.vsix”
