There several solutions we recommend if, when attempting to open a company file, the following error appears:

We're sorry. QuickBooks encountered a problem. Error codes: (-6000, -77).

 
Possible quick fixes:
  • Re-launching QuickBooks Desktop with elevated permissions may resolve the issue. Right-click the QuickBooks Desktop icon on your desktop and select Run as Administrator.
  • If the company file is saved on an external drive, copy the company file locally.
