How to fix Error 6189, 816

Learn what Error -6189, 816 is and what to do if you see it in QuickBooks Desktop.

If you see the message “An error occurred when QuickBooks tried to access the company file (-6189, -816),” don’t worry. There’s an issue with your multi-user network, not with your accounting data.

Here’s how to get your QuickBooks Desktop multi-user network up and running again.

Solution 1: Run Quick Fix my Program from the QuickBooks Tools Hub

Step 1: Download and install the QuickBooks Tools Hub

The QuickBooks Tool Hub helps fix common errors.  For the best experience, we recommend using Tool Hub on Windows 10, 64-bit.

  1. Close QuickBooks.
  2. We recommend you download the most recent version ( of the QuickBooks Tool Hub. Save the file somewhere you can easily find it (like your Downloads folder or your Windows desktop). Note: If you've already installed Tool Hub before, you can find out which version you have. Select the Home tab.  The version will be displayed on the bottom right or you can select About to view the version.
  3. Open the file you downloaded (QuickBooksToolHub.exe).
  4. Follow the on-screen steps to install and agree to the terms and conditions.
  5. When the install finishes, double-click the icon on your Windows desktop to open the tool hub.


Note: If you can't find the icon, do a search in Windows for QuickBooks Tool Hub and select the program.


Step 2: From the Tools Hub, run the Quick Fix my Program

  1. In the QuickBooks Tools Hub, select Program Problems.
  2. Select Quick Fix my Program.
  3. Start QuickBooks Desktop and open your data file.

If you still see Error -6189, 816, move on to Solution 2.

Solution 2: Restart all of your computers and servers

Sometimes your whole system needs a full reset. Follow these steps in order.

  1. Restart your server computer (the one hosting your company files).
    Important: Where is your company file hosted?

    If you’re using  instead of a server computer, reach out to us through chat so we can help you restart.

    If you use one of our affiliated Intuit Hosting Providers or another cloud service to host your company files, contact them for help restarting the service.

  2. Restart each workstation (the other computers connected to the network that don’t host your company files).
  3. Open QuickBooks Desktop on your server computer.
  4. Open QuickBooks Desktop on each workstation.

If QuickBooks opens, you’re good to go. If you still see Error -6189, 816, move on to Solution 3.

Solution 3: From the Tools Hub, run the QuickBooks Database Server Manager on your server

Your server computer is the one that stores your QuickBooks company file(s). Your other computers connected to your network are your workstations. If you’re hosting your own network, QuickBooks Database Server Manager will help keep your multi-user network stable.

  1. In the tools hub, select Network Issues.
  2. Select Quickbase Database Server Manager. You’ll be asked to install QuickBooks on your server if it isn’t already installed.
  3. Inside the QuickBooks Database Server Manager, Select Start Scan if you see your company file(s). If they aren’t, Browse to the location of your company file and then select Start Scan.
  4. The QuickBooks Database Server Manager will repair your firewall permissions automatically. When the scan finishes, select Close.
  5. Open QuickBooks Desktop on your server computer and workstations.
Note: If QuickBooks Database Server Manager is installed on one of your workstations, make sure the workstation isn’t set to host your multi-user network.

Solution 4: Move your company files to your local hard drive

If you still see the Error -6189, 816 and your company file (.QBW) is currently stored on a removable drive or online, move your company files to your local hard drive.

Important best practices:

Store QuickBooks files, including your company file, on your server computer’s hard drive. Online file hosting services like Dropbox, Google Drive, and are convenient, but they can cause issues.

Don’t store files on removable or external drives. External hard drives, USB flash drives, and Network Attached Storage [NAS] devices aren’t designed to run QuickBooks or multi-user networks.

Don’t encrypt your QuickBooks files or the hard drive storing them. This can block your multi-user network connection.
