How to remove an old Corona Renderer version before installing a new one?

You do not have to do this. Just run the Universal Installer and proceed with the installation as usual. This will delete all files associated with any previous Corona version and run a new, clean installation. 

If you would like to uninstall Corona Renderer for some reason, you can do it:

Windows users,

  • Automatically - by going to the "Add or remove programs" feature in Windows and finding Corona Renderer.
  • Manually - by removing all Corona Renderer files. For the list of files, see: How to install Corona Renderer manually?

Mac users, 

(The remove Corona script can be accessed from here: remove_corona)

Please do the following to run the remove_corona script:

  • Download and save the file onto your local drive (it could be at Desktop or any other folder)
  • Right-click on the script file.
  • Hover over the Open With option.
  • Choose Other....
  • Locate the Applications folder, then open the Utilities folder, and select the Terminal app.
  • If you can't select the Terminal app, change the enabled applications from Recommended Applications to All Applications. (It is at the bottom of the window)
  • If you want to open every ".command" file with the Terminal app, tick the Always Open With option.
  • Press the Open button in the bottom right corner of the window.

Troubleshooting (Mac users)

If for any reason you're not able to run the script due to OS permission restrictions, please do the following steps to allow the system to run the script:



  • Move the "remove_corona.command" file to a known location (e.g., Desktop)
  • Open the Terminal (you can find it in your Applications folder or using the Spotlight search).

  • Navigate to the folder where the script is located using the command "cd" to move to another folder.
    (Don't forget to use the commands without the quotes.)
    For this example, we've placed the file on the Desktop. So we need to type "cd Desktop" (without the quotes) and hit the Enter key on your keyboard.
  • Once you're in the same folder where the script is located, please type the following to set the file permissions and hit the Enter key:
    chmod 755 remove_corona.command
  • Next, you'll need to type the following as well and hit the Enter key once you've finished writing the command: chmod +x remove_corona.command

  • Now you can close the Terminal.
  • Next, double-click on the "remove_corona.command" file to open. The Terminal will ask for your mac user password, please type it and hit the Enter key.

  • Wait for the process to be completed, and then close it.
