OK here is a link for the installer if anybody wants to try it out. Its a simple C# console app that will install pyRevit 4 and 5 (installers are bundled) and then execute the necessary terminal commands to attach to Revit.
You can choose to install the latest pyRevit 4 for Revit 2020 - 2024 and pyRevit 5 for 2025, or pyRevit 5 for 2020-2025. You could just use the pyRevit 5 installer directly if you wanted to use for every version, but I figured I’d make it an available option anyways because it allows you to easily switch between pyRevit 5 only and both 4 and 5 side by side.
