Understanding NG Issues


Typical NG Opening Challenges

Norton Desktop is Not Installed

If you attempt to load your NG file, you experience a message such as "Can't Open NG Files". If so, it typically means that you don't have Norton Desktop installed for %%os%%. Your operating system cannot associate your NG with Norton Desktop, so double-clicking the file won't work.


Tip: If you have another software that you know opens NG files, you can select it by hitting the "Show Apps" button.


Incorrect Norton Desktop Version

Your Norton Guide Online Documentation Database file is incompatible with Norton Desktop because you might have the wrong version installed. Visit the Symantec Corporation website to download (or purchase) the latest version of Norton Desktop. Your Norton Guide Online Documentation Database file was probably created by a newer release of Norton Desktop than what's currently installed your computer.


Tip: Sometimes you can get a clue about the version of NG file you have by right clicking on the file, then clicking on "Properties" (Windows) or "Get Info" (Mac OSX).


Summary: In either case, the majority of problems opening NG files are related to not having the correct software application installed on your computer.


Additional NG Opening Issues

You can still experience errors opening NG files even with the latest version of Norton Desktop installed on your PC. Other NG opening errors can be created by other system problems inside of %%os%%. Additional factors include:

  • Invalid NG file references in the Windows Registry (the "phonebook" of the Windows Operating System)
  • The NG file description within the Windows Registry was removed
  • Incomplete or bad installation of a software application associated with the NG format
  • Your NG file is corrupted (issues with your Norton Guide Online Documentation Database file itself)
  • Your NG has adversely impacted by malware
  • Device drivers of the hardware associated with your NG file are corrupt or out-of-date
  • Your PC doesn’t have enough available resources to open the Norton Guide Online Documentation Database file
