You can install Pega Robot Studio v21 Preview on a machine that houses Robot Studio 19.1.

However, please be aware of the following:

• You must install 19.1 before installing the v21 Preview.
• Do not install 19.1 and Robot Studio v21 Preview in the same folder.
• The 19.1 and v21 Preview versions both use the same extensions for Chrome and Edge. After an install or uninstall, check the status of the extensions you plan to use to make sure they are properly installed and enabled.
• Both version 19.1 and v21 Preview require Pega Native Foundation. It is not necessary to reinstall Pega Native Foundation if it is already installed.
