"Setup has detected that Visual Studio 2015 Update 3 may not be completely installed...."

Question

"...Please repair Visual Studio 2015 Update 3, then install this product again."

I'm getting this when I try and update the ASP.NET Web Tools Extension in my version of VS 2015 which I installed only today. After I got this error I checked and my version was Update 3. I tried to install it regardless and got a message saying that I already had it.

Any ideas on how I can get around this issue?

Ok after some digging I got to the bottom of this. It seems that I need to have .Net Core Installed. However when I go to install that I get the same error. The workaround is to run the downloaded .exe from the command line with the added parameter:

DotNetCore.1.0.0-VS2015Tools.Preview2.exe SKIP_VSU_CHECK=1

This will install the latest version of Web Tools as well.
