Whenever I run root from the Command Prompt in Windows 10, I get the following the errors:

I am using root version Release 6.18/02. I am also using Visual Studio 2019.

After getting these errors, I am still able do a few simple commands using root like cout<<“Hello World”<<endl; .

Hi,

This is a known issue, when one is using a different version of the Windows Kit than the one used when building ROOT (10.0.17763.0 vs 10.0.18362.0). We will try to find a solution

Cheers, Bertrand.

Should I continue using this version of the root then?

Yes, if it works… Otherwise you can try to build ROOT from source with your own version of Visual Studio…
