  <pre><code>[!] Visual Studio - develop for Windows (Visual Studio Community 2019 16.4.5)
      X Visual Studio is missing necessary components. Please re-run the Visual Studio installer for the "Desktop
        development with C++" workload, and include these components:
          MSBuild
          MSVC v142 - VS 2019 C++ x64/x86 build tools
           - If there are multiple build tool versions available, install the latest
