Root 6.18.04 Startup Problem

[Martin_lky]

ROOT Version: 6.18.04
Platform: Windows 10 -x64
Compiler: Visual Studio 2019

After I installed visual Studio 2019 and ROOT, I run root on terminal and received this error:

Hi,

This is a known issue. Try to install the Windows 10 SDK version 10.0.17763.0 (or 10.0.18362.0 - just check which one is missing) with the Visual Studio Installer. If it doesn’t work, you can try to use one of the nightly builds, for example root_v6.19.01.win32.vc16.debug.zip or root_v6.19.01.win32.vc16.zip (or the executables) and if it still doesn’t work, I’m afraid you’ll have to build from source…

Cheers, Bertrand.
