For this update, it's okay to skip reinstalling vscode, JDK, and the compiler if you already installed them with 2019.1.1, 2019.2.1 or 2019.3.2.
After you install the update, vscode will prompt you when opening an older project whether or not you want to upgrade it to 2019.4.1.
Installing Visual Studio Code
Visual Studio Code (vscode) is the recommended and supported IDE. However, it requires a separate download as part of the install process. Make sure to click the "Select/Download" button during the install process if you want to install vscode.
If you need to install vscode on an offline machine, run the installer first on an Internet-connected machine and click the "Select/Download vscode" button. Then copy both the installer and the downloaded OfflineVsCodeFiles zip file to the offline machine.
