QuickBooks Error 6189 and 816 means QuickBooks Desktop cannot access your company file due to a database or multi-user connection issue, usually involving your .QBW/.TLG files, hosting, or network setup.
What the error means
What the error means
- The message typically says: “An error occurred when QuickBooks tried to access the company file (-6189, -816).”
- It is commonly linked to a mismatch or problem between the company file .QBW.QBW and its transaction log .TLG.TLG, or the file being in use incorrectly in multi-user mode.
- Improper multi-user hosting (hosting turned on at workstations instead of only on the server).
- Damaged or out-of-sync .ND (network) or .TLG (transaction log) files associated with the company file.
- Incorrect Windows permissions on the folder containing the company file or firewall/antivirus blocking QuickBooks services.
- Restart the server computer that stores the company file, then restart each workstation and try opening the file again.
- Make sure the company file is on a local server drive, not on a mapped network drive to a workstation or in cloud-sync folders like OneDrive/Google Drive/Dropbox.
- Install and run the QuickBooks Tool Hub , then use “Quick Fix my Program” and “Company File Issues” as guided to auto-repair common company file and program issues.
- From Tool Hub, go to Network Issues and run QuickBooks Database Server Manager on the server to scan the company file folder and repair firewall/hosting settings.
- Rename the .ND and .TLG files (QuickBooks will recreate them) and ensure Windows folder permissions give full control to the QB data service user and your Windows users.
- If none of these steps work, contact official Intuit QuickBooks support directly through your product or the Intuit support site rather than third-party phone numbers posted in forums. Official warns that random “support” phone posts can be spam or guidance unsafe.
