Using Jupiter in Design 5.4.5



  1. Go to and install the latest LTS version of NodeJS.
  2. Open "node.js command prompt" from the windows programs, use the command "cd [your /jupiter/app directory]". Then use the command "npm install" - update instruction when build is released -
  3. Open Design 5.4 and navigate to "Options" -> "Settings" ->"Jupiter"
  4. Setting : "path for Jupiter.js" (required) 
  5. Setting : socket port and Web port. (optional)If the default 3000 and 3500 ports are already in use by another program on your computer, you can change it there.
  6. Setting : "Path for node.js executable" (required) : By default, node is installed in C:\Program Files\nodejs\node.exe
  7. Setting (optional): in the "verification" section, I recommend setting "Automatically verify / generate screens" to "Yes"


  • From the screen mode, use the "Jupiter" icon next to the "IE testing" icon.

    This will effectively emulate a Webprod, thus allowing you to test your questionnaire from your local network, in any browser.
  • You can copy the URL from your browser and use it in any other browser, would you want to test the questionnaire's screens from various browsers.
  • Once your questionnaire is running on the local emulator, any change applied to the .qex (even without saving them) will be reflected after a browser refresh
  • Use the menu "screens"->"show URL for Jupiter testing" to get all the addresses at which the Jupiter emulator will be accessible. This will allow you to access the screens from your local network (smartphone connected to the same network, other computer...)
