In this comprehensive guide, we will cover everything you need to know about QuickBooks Error 6190 on Windows 10, including its causes, troubleshooting steps, and preventive measures. What is QuickBooks Error 6190? QuickBooks Error 6190 is part of the 6000-series errors, which are related to issues with company files.

This issue primarily arises when the company file (.QBW) and its associated transaction log file (.TLG) are out of sync, or when another user is already logged into the company file in single-user mode. Common Symptoms of QuickBooks Error 6190 When QuickBooks Error 6190 occurs, you may notice the following symptoms: ● ● ● ● The error message appears on your screen while attempting to open a company file.

2. Several factors can lead to QuickBooks Error 6190 on Windows 10, especially in a multi-user environment. Below are some of the most common causes: 1. Mismatch Between the .QBW and .TLG Files QuickBooks creates a transaction log file (.TLG) every time changes are made to the company file (.QBW). If these two files become unsynchronized due to improper closing of the software, system crashes, or failed updates, QuickBooks might throw Error 6190 when trying to access the company file. 2. Another User is Logged In Single-User Mode QuickBooks Error 6190 can occur when one user is logged into the company file in single-user mode, but another user tries to access the file in multi-user mode. This conflict prevents the second user from accessing the file and causes the error. 3. Corrupted or Damaged Company File A corrupt or damaged company file can also trigger Error 6190. This damage can be caused by abrupt system shutdowns, virus infections, or hardware failures that affect the integrity of the file. 4. Network Connectivity Issues Since Error 6190 is common in multi-user environments, problems with network configuration or connectivity between the server and workstations can prevent QuickBooks from accessing the company file. Firewalls or security settings that block communication between systems can also cause this error. 5. Multi-User Mode Not Set Up Correctly QuickBooks Error 6190 can also arise if multi-user mode is not set up properly on the server or the client workstations. Misconfigurations or improper installations can lead to file access issues. How to Fix QuickBooks Error 6190 on Windows 10 There are several methods you can try to resolve QuickBooks Error 6190. Below are detailed step-by-step instructions for each solution. Be sure to follow these steps carefully to ensure a successful resolution.

Solution 2: Rename the .TLG and .ND Files Another method to resolve QuickBooks Error 6190 is to rename the .TLG (transaction log) and .ND (network data) files associated with your company file. These files store crucial data for QuickBooks, and renaming them can often fix file access issues. 1. Locate the Files: ○ ○ Open the folder where your QuickBooks company file is stored. Look for files with the same name as your company file but with extensions .TLG and .ND. For example, if your company file is named CompanyFile.QBW, the associated files will be CompanyFile.TLG and CompanyFile.ND. 2. Rename the Files: ○ Right-click on the .TLG file and choose Rename. ○ Add the word OLD at the end of the file name (e.g., CompanyFile.TLG.OLD). ○ Do the same for the .ND file (e.g., CompanyFile.ND.OLD). 3. Restart QuickBooks: ○ After renaming these files, open QuickBooks and try to access the company file. New .TLG and .ND files will be automatically generated when you reopen QuickBooks. Solution 3: Verify and Rebuild the Company File Verifying and rebuilding the company file can help fix data corruption issues that may be causing QuickBooks Error 6190. 1. Open QuickBooks in Single-User Mode: ○ Ensure that no other users are logged into QuickBooks.

4. Go to the File menu and select Switch to Single-User Mode. 2. Run the Verify Data Utility: ○ From the File menu, choose Utilities. ○ Select Verify Data.

Be sure to create a backup of the file before rebuilding it. 4. Restart QuickBooks: ○ After the rebuild process is complete, restart QuickBooks and check if the error is resolved. ○ Solution 4: Ensure Proper Multi-User Mode Setup If QuickBooks Error 6190 occurs because of an incorrect multi-user mode setup, ensuring proper configuration can resolve the issue. 1. Check the Server Configuration: ○ On the server hosting the QuickBooks company file, open QuickBooks and go to File > Utilities. ○ Make sure that Host Multi-User Access is selected. If you see Stop Hosting Multi-User Access, then the system is already set up correctly. 2. Check the Client Workstations: ○ On each workstation, open QuickBooks and go to File > Utilities. ○ Make sure that Host Multi-User Access is NOT selected. If you see Stop Hosting Multi-User Access, click on it to disable hosting on that workstation. 3. Restart the Server and Workstations: ○ After making these changes, restart both the server and all workstations and try accessing the company file again.

Allow QuickBooks Through the Firewall: ○ Open Control Panel and go to System and Security > Windows Defender Firewall. ○ Click on Allow an app or feature through Windows Defender Firewall. ○ Make sure QuickBooks is on the list of allowed applications and is enabled for both Private and Public networks. 2. Configure Antivirus Exceptions: ○ Open your antivirus software and configure it to allow QuickBooks processes like QBW32.exe to run without interference. 3. Test the Connection: ○ Once the firewall and antivirus settings are adjusted, restart QuickBooks and see if the error persists.
