A few other alternatives for running external apps on Windows

SketchUp Ruby API’s UI::openURL can start executables.

Example: from the Ruby Console in SketchUp 2022 I call this …

UI.openURL("file:///C:/Program Files/SketchUp/SketchUp 2017/SketchUp.exe")

… and after a few seconds an instance of SU2017 is loaded. (I have like 6 versions of SketchUp installed.)

Another example:

UI.openURL("file:///C:/Windows/notepad.exe")

… opens an instance of Window’s Notepad editor.

The Windows Scripting Host Shell Object can be used from within SketchUp using Ruby’s WIN32OLE library.

require 'win32ole'
shell = WIN32OLE.new("WScript.Shell")

shell.Exec("calc")

… or …

shell.Run "cmd /K CD C:\ & Dir"
