When I was trying to install ASP.NET Web Tools Preview 2 for DotNetCore on Visual Studio 2015, I got this error message. I have installed VS2015 Update 3 as required.
Then I followed the instruction to repair VS2015 Update 3. Still had the same error. I even uninstalled VS2015 completely. Then installed VS2015 again. But it was still the same. After searching online a little bit, looks like this is not a rare issue. And found out there are actually some options you can pass to the installation program. And solved this error.
The installation file is: DotNetCore.1.0.0-VS2015Tools.Preview2.exe. If you run:
DotNetCore.1.0.0-VS2015Tools.Preview2.exe /? |
You can see some options like this:

It still doesn’t seems to have an option for solving this error. But you can run this also with parameter SKIP_VSU_CHECK=1:
DotNetCore.1.0.0-VS2015Tools.Preview2.exe SKIP_VSU_CHECK=1 |
Now the magic just happened. No more errors.
