"Application not found" when running a CD or DVD


When you insert a disc into your computer or try to open it from My Computer you get the following error:


Application not found”

The disc may open without error if you right click the drive and select the Open or Autoplay option.


This can be the fault of a bad registry entry.


  1. Click the Start button (then click Run if using Windows XP)
  2. Type regedit and press Enter.
  3. Navigate to: HKEY_CURRENT_USER > Software > Microsoft > Windows> CurrentVersion > Explorer.
  4. Delete the MountPoints2 item.
  5. Restart the computer.
