How do I start Visual Studio after installation?

If you have Visual Studio open, go to Tools > Get Tools and Features... which opens the Visual Studio Installer. Or, open the Visual Studio Installer from the Start menu.

Do I need to uninstall Visual Studio 2017 before installing 2019?

Starting from Visual Studio 2017, Community, professional and Enterprise editions can install side by side. The installation will not attempt to uninstall older versions and we don't need to uninstall older version of VS 2015/2017, before installing the VS2019.

Can I have Visual Studio 2017 and 2019 installed at the same time?

You can install and use Visual Studio 2019 alongside previous versions of Visual Studio, including Visual Studio 2017, Visual Studio 2015, Visual Studio 2013, and Visual Studio 2012.

remove this folder (or similar):

%LocalAppData%\Microsoft\VisualStudio\15.0_db2a872f

  • folder name 15.0_db2a872f could be different in your machine eg. 15.0_XXXXXXX
  • found in the vs startup log that processing of Progression_NativePackage_Component_x86.pkgdef bailed out, indicating an inconsistent extension installation
