is there any way to see the error messages in the setup, particularly in the component selection window?
I only see e.g.
Microsoft Visual Studio 2015 Shell* can not be installed because
Intel Debugger Extension 7.12 will not be installed, since this component
which is really not helpful without the rest of the text!
Thanks for any advice.
The debugger extension message can be ignored, unless you will be developing applications for Intel Xeon Phi coprocessors.
My guess on the Shell issue is that you don't have the required Windows SDK installed. See https://software.intel.com/en-us/vs2013shell-windowssdk - I know it says VS2013 Shell but I am fairly certain that the same issue applies to VS2015 Shell.
Normally one can see more of the message in the window, but there should have been an earlier screen with more text on the issues.
Thank you, Steve. Installing the latest Windows 10 SDK did the trick. I have successfully run the setup (now it miraculously shows the complete error messages after clicking on them - I don't know why it did not work the first time).
