The above error message is displayed and SuperNova fails to magnify the screen. Restarting the PC fails to resolve the issue.


This issue may occur if there is a “Dameware Mirror Driver” present on the system. This is a mirror driver used to support Dameware remote control software. To work around this issue:


  1. Open the Windows 10 “Start” menu
  2. Type Device Manager into the search field.
  3. From the search results, choose “Device Manager”
  4. In the Device Manager window, expand “Display Adapters”
  5. If “Dameware Mirror Driver” is present, RIGJT CLICK and choose “Disable”.
  6. Restart the PC.


The problem should now be resolved.
