What Is QuickBooks Error 6190?
QuickBooks Error 6190 usually appears when a user tries to open a company file that’s already being accessed in another mode or when there’s a mismatch between transaction log files and company files.
You may see messages such as:
- “QuickBooks is unable to open this company file.”
- “Error codes: (-6190, -816)”
- “Another user is logged into the company file.”
This problem commonly occurs in network environments where multiple users access the same QuickBooks company file.
In some situations, the issue may also appear alongside a QuickBooks Network Connection Error, making it difficult for workstations to communicate with the server properly.
Common Symptoms of QuickBooks Error 6190
Here are some common signs users experience before or during the error:
- QuickBooks freezes while opening the company file
- Multi-user mode stops working
- Users can’t access shared company data
- Slow performance over the network
- Payroll processing interruptions
- Unexpected crashes while switching files
Some users also report related problems like QuickBooks Error the file exists during updates or company file access attempts.
Main Causes of QuickBooks Error 6190
Understanding the root cause makes troubleshooting easier. Below are the most common reasons this error occurs.
1. Company File and Transaction Log File Mismatch
QuickBooks stores company data in a .QBW file and transaction logs in a .TLG file. If these files don’t sync correctly, QuickBooks may block access to protect data integrity.
2. Multiple Users Accessing the File Incorrectly
If one user opens the company file in single-user mode while others try multi-user access, conflicts can trigger QuickBooks Error 6190.
3. Damaged Network Configuration
A weak or unstable network setup may cause a QuickBooks Network Connection Error, interrupting communication between systems.
4. Corrupted Company File
Damaged data files can stop QuickBooks from reading financial records properly.
5. Windows Permission Issues
If the user account doesn’t have enough permission to access the company file folder, QuickBooks may display the error.
6. Interrupted Updates or Payroll Sync Problems
Failed payroll updates or QuickBooks direct deposit issues can sometimes affect company file operations and trigger related errors.
Step-by-Step Solutions to Fix QuickBooks Error 6190
Follow these troubleshooting methods carefully. After each step, try reopening the company file.
Solution 1: Verify All Users Are Logged Out
This is the simplest and often the most effective fix.
- Close QuickBooks on every connected workstation.
- Restart all systems connected to the network.
- Open QuickBooks only on the server computer first.
- Try accessing the company file again.
If you’re unsure which workstation is causing the conflict, disconnect all users temporarily.
Solution 2: Rename the .ND and .TLG Files
QuickBooks automatically recreates these files.
Steps:
- Open the folder containing your company file.
- Locate files ending with:
- .ND
- .TLG
- Right-click each file and choose Rename.
- Add .OLD at the end.
Example:
- CompanyFile.qbw.nd → CompanyFile.qbw.nd.old
Now reopen QuickBooks and test the file.
If the error continues, don’t risk your financial data—contact support now at +1 (855)-510-6487 for professional assistance.
Solution 3: Use Single-User Mode Properly
Sometimes users accidentally switch modes incorrectly.
- Open QuickBooks on the host computer.
- Go to File > Switch to Multi-user Mode.
- Ensure no other user has the file open in single-user mode.
This can also help resolve related QuickBooks Network Connection Error issues.
Solution 4: Copy the Company File to Local Desktop
This step helps determine if the network is causing the issue.
- Copy the .QBW company file.
- Paste it onto the desktop.
- Open QuickBooks.
- Browse to the copied file and open it.
If the file opens locally, the problem likely involves network configuration.
Solution 5: Update QuickBooks Desktop
Outdated software can create compatibility issues.
To update QuickBooks:
- Open QuickBooks.
- Go to Help > Update QuickBooks Desktop.
- Select Update Now.
- Install updates and restart the program.
Some users experiencing QuickBooks direct deposit issues have resolved company file problems after completing pending updates.
Solution 6: Check Windows Folder Permissions
QuickBooks needs full access to the company file folder.
Steps:
- Right-click the company file folder.
- Select Properties.
- Open the Security tab.
- Ensure all QuickBooks users have:
- Full Control
- Read/Write permissions
Apply changes and reopen QuickBooks.
