Solved – QuickBooks is unable to open Error Codes: -6190, -816

Customer got this error.

QuickBooks is unable to open this company file. It may have been opened by another user.


We had all the users log out, but the single user trying to get was getting the error.

What I did to fix it was to log onto the server, run services, and restarted all the quickbook services.

  • QuickBooksDB22
  • QuickBooksDB25
  • QBCFMonitorService – This service was not running though set to start automatically. Starting this service got it working correctly.


I hope this helps someone else out there…


Quickbooks – Unrecoverable Error – Solved

We had a client who’s Quickbooks suddenly stopped working properly. When the program would start to open there was an error thrown.

“We apologize for the inconvenience. Please help the QuickBooks team eliminate this issue by providing us with the following information.”


This was solved by repairing the program. I went into add/remove programs. Selected Quickbooks and clicked uninstall. Through this process I was given the choice to repair. When the repair process was finished the program ran normally.

I hope this helps someone else out there.
