Steps to Fix QuickBooks Error Code 6190, 816​

Step 1: Rename the .ND and .TLG Files​

The .ND (Network Data) and .TLG (Transaction Log) files are configuration files that help QuickBooks access the company file in a multi-user environment. Renaming these files forces QuickBooks to recreate them, which can resolve access issues.

  1. Locate the Company File:
    • Navigate to the folder where your company file is stored. The file typically has a .qbw extension.
  2. Find the .ND and .TLG Files:
    • Look for files with the same name as your company file but with .ND and .TLG extensions (e.g., CompanyName.qbw.nd and CompanyName.qbw.tlg).
  3. Rename the Files:
    • Right-click on each file and select Rename.
    • Add .old at the end of the file names (e.g., CompanyName.qbw.nd.old and CompanyName.qbw.tlg.old).
  4. Retry Opening the File:
    • Open QuickBooks and try accessing the company file again.

Step 2: Use QuickBooks File Doctor​

QuickBooks File Doctor is a powerful tool that can detect and repair file-related issues.

  1. Download QuickBooks Tool Hub:
    • Visit Intuit’s official website and download the latest version of QuickBooks Tool Hub.
  2. Open Tool Hub:
    • Launch the Tool Hub and navigate to the Company File Issues tab.
  3. Run QuickBooks File Doctor:
    • Click Run QuickBooks File Doctor and select your company file.
    • Let the tool scan and repair the file.
  4. Retry Accessing the File:
    • Open QuickBooks and attempt to access the file again.

Step 3: Verify Hosting Settings​

Ensure that the hosting settings are correctly configured on both the server and workstations.

  1. On the Server:
    • Open QuickBooks on the server computer.

  2. On the Workstations:
    • Open QuickBooks on each workstation.
    • Navigate to File > Utilities.
    • Ensure that Host Multi-User Access is disabled. If it says Host Multi-User Access, do not enable it.

This error often occurs when another user opens the company file in single-user mode.

  1. Switch to Multi-User Mode:
    • Open QuickBooks on the server computer.
    • Go to File > Switch to Multi-User Mode.
  2. Close the File on Other Systems:
    • Ensure no other users are accessing the file in single-user mode.
  3. Retry Accessing the File:
    • Attempt to open the company file from your workstation.

Step 5: Update QuickBooks Desktop​

Using the latest version of QuickBooks Desktop ensures compatibility and reduces errors.
