The Fix
The issue seems to be generated by the fact that VS Studio 2015 Update 3 is not correctly seen by the setup executable, thus making the internal checks erroneously fail.
Luckily enough, there's a simple workaround we can use to skip these checks by using a command-line parameter that does just that.
To get past the issue open a command prompt, navigate through the folder where you downloaded the Microsoft .NET Core 1.0.0 VS2015 Tooling Preview Update 2 executable file and type the following:
|
1 |
dotnetcore.1.0.0-vs2015tools.preview2 SKIP_VSU_CHECK=1 |
As soon as you hit ENTER, the setup program will start by skipping the erroneous Visual Studio Update checks, allowing you to install the package.
That's it for now: happy update!
