In most cases, your version of the ARIA Engine should match the version of the ARIA Player (see this article for an explanation of the difference between the two). Your ARIA Engine version will be higher if you own both Garritan Abbey Road Studios CFX Concert Grand and a separate Garritan library. If you need to roll back for compatibility reasons, follow these steps: 


  1. Press the WINDOWS key on your computer keyboard; type "Programs and Features".
  2. Choose the Programs and Features option that appears.
  3. Find the ARIA Engine in the list of programs that appears.
  4. Right-click ARIA Engine [version number] and choose Uninstall.
  5. Follow the prompts to uninstall the ARIA Engine.
  6. Repeat steps 3 - 5 for the ARIA Player [version number] to uninstall the ARIA Player.

You can now reinstall a previous version of the ARIA Player.



  1. Download the ARIA_Uninstaller attachment found at the bottom of this article.
  2. Extract the file to your desktop and double-click on it to start.

    Mac users with OS X 10.8 or later may need to adjust their System Preferences if the uninstaller is blocked by GateKeeper.

  3. Choose ARIA Player from the pop-up menu.
  4. You will be shown the list of the files to be removed. Take a minute to browse through the list in case
    you have put personal files in the ARIA product folder(s) by mistake.
  5. Click Remove.
  6. Repeat steps 3-5, choosing ARIA Engine from the pop-up menu.

You can now reinstall a previous version of the ARIA Player.
