After Windows 10 has updated with the April 2018 Update (1803) SuperNova may display a "Magnification Engine Failed to Start. Code 7" error message depending on the Display Adapter in your device.


There are a number of ways in which you can resolve this issue:

  1. Import the "DisableOverlays" registry key from the zip file and then restart your computer, the registry key is available to download from
  2. Download and reinstall the SuperNova web demo from the Dolphin website - choose the "Legacy Downloads" if you are not currently running the latest version.
  3. Update to SuperNova v20.01 or later (you will require a valid license) and ensure you have restarted the PC after the install.
