I think the issue may be I already had this installed, but when I open my Visual Studio Extensibility project (Regionizer,http://regionizer.codeplex.com/ ) Visual Studio showed me this message:
So I click the button to install and I get this screen:
So I do as instructed and click Install, then I see this message with no other explanation of what to do:
Not a single word is mentioned about what this setup is (which file), or how I go about installing it.
I was able to rebuild this project a couple of weeks ago so I know I have everything installed; I went to go publish an update for my open source project and that is when I noticed the above message.
After I click 'Ok' the setup goes away, and the message is shown again the next time I open Visual Studio.
In case this helps the VS team, I am using VS Enterprise 2015, Windows 10.
Please tell me what the fix is.
