Error reading source file in NL220


When closing out NL220, an automatic prompt comes up asking 'Do you want to make a backup of the project?". After selecting yes, the message "Error reading source file." is displayed.



  • NL220
  • Vista


Error reading source file is a result of creating a NL220 backup while running Vista server.


There are two ways to avoid this error.

  1. Shut down Vista server before closing down NL220 and selecting to make a backup.

  2. With Vista server and NL220 still running, go to the menu bar and select Project > Backup project...

    In the Backup a project... screen, select Backup.
