QuickBooks Desktop is an essential accounting tool for many businesses, but errors can sometimes interrupt your workflow. One common problem that users face is QuickBooks Error 6190, which appears when trying to access a company file. This issue prevents you from opening the file in either single-user or multi-user mode and disrupts day-to-day operations.

If you are stuck with this error and need immediate help, you can call 1-888-394-9046 or 1-866-596-1988 for expert QuickBooks support. This guide explains all causes, symptoms, and solutions in detail to help you fix the problem completely.

What Is QuickBooks Error 6190?

QuickBooks Error 6190 occurs when QuickBooks Desktop cannot open the company file stored on the network or local drive. Usually, it appears with this message:

“QuickBooks is unable to open the company file. Error 6190.”

This error often occurs together with Error 816, especially when the transaction log file does not match the company file.

If you want fast troubleshooting or cannot afford downtime, call 1-888-394-9046 or 1-866-596-1988 for direct assistance.

Why Does QuickBooks Error 6190 Occur?

Understanding the causes helps you resolve the issue more efficiently. The main triggers include:

1. Mismatch Between the Company File (.QBW) and the Transaction Log File (.TLG)

When the .TLG file does not match the .QBW file, QuickBooks cannot open the company data, causing Error 6190.

2. Damaged or Corrupted Company File

If the company file has internal corruption, QuickBooks may fail to open it.

3. Incorrect Multi-User Mode Setup

This error often appears on a network where multiple users try to access the file simultaneously but the hosting configuration is wrong.

4. Company File Opened in Single-User Mode on Another System

If someone opened the file in single-user mode on one computer, others will not be able to access it.

5. Network Server Problems or Damaged ND File

The ND (Network Data) file helps QuickBooks communicate across the network. A damaged ND file leads to Error 6190.

6. Incomplete QuickBooks Installation

If installation files are damaged or missing, QuickBooks may not open the company file.

7. Malware or Unauthorized Changes

Viruses or external programs may damage QuickBooks files or block access.

If any of these issues are affecting your work, immediate help is available at 1-888-394-9046 or 1-866-596-1988.

Solution 2: Fix the Mismatch Between .QBW and .TLG Files

This is one of the most effective ways to eliminate Error 6190.

Steps:

1. Go to the folder where the company file is stored.
   
   

2. Locate both files:
   
   

   • Company file: yourcompanyname.QBW
     
     

   • Transaction Log file: yourcompanyname.TLG
     
     

3. Rename the .TLG file:
   
   

   • Right-click → Rename
     
     

   • Add .old at the end (example: companyname.tlg.old)

5. Open QuickBooks again.
   
   

If you still cannot open the file, call 1-888-394-9046 or 1-866-596-1988 for help re-syncing the files.

Solution 3: Rename the ND File (Network Data File)

A damaged ND file often causes QuickBooks network errors.

Steps:

1. Go to the folder where your company file is located.
   
   

2. Find the file yourcompanyname.ND.
   
   

3. Right-click and rename it:
   
   

   • Add .old at the end.
     
     

4. Open QuickBooks Database Server Manager.
   
   

5. Rescan the folder.
   
   

If the company file still won’t open, you can get help from a QuickBooks technician at 1-888-394-9046 or 1-866-596-1988.

Solution 4: Ensure Proper Multi-User Hosting Setup

Incorrect hosting settings can block multi-user access.

Fix it by checking hosting on each computer:

1. Open QuickBooks.
   
   

2. Go to File → Utilities.
   
   

3. On the server computer:
   
   

   • Make sure Host Multi-User Access is enabled.
     
     

4. On workstations:
   
   

   • Make sure Stop Hosting Multi-User Access is selected.
     
     

If hosting and permissions confuse you, call 1-888-394-9046 or 1-866-596-1988 for multi-user mode support.

Solution 5: Copy the Company File to Another Location

This helps identify whether the issue is with the file or the storage device.

Steps:

1. Copy the company file (.QBW) from the original location.
   
   

2. Paste it on your desktop.
   
   

3. Open QuickBooks and browse to open the file.
   
   

If the file opens, your storage drive or network path has issues.
If it still fails, the file may be corrupt. You can get file repair assistance at 1-888-394-9046 or 1-866-596-1988.

Solution 6: Restart All Network Devices

A network glitch may cause QuickBooks Error 6190.

2. Turn off all workstations.
   
   

3. Restart the modem and router.
   
   

4. Turn the server back on.
   
   

5. Turn on client computers one by one.
   
   

Retry opening your company file.
If the error persists, call 1-888-394-9046 or 1-866-596-1988 for professional diagnosis.

Solution 7: Perform a QuickBooks Clean Install

A clean installation replaces damaged QuickBooks program files.

Steps:

If reinstalling seems complicated or errors reappear, call 1-888-394-9046 or 1-866-596-1988 for installation support.

Solution 8: Check for Company File Corruption

If your company file is damaged, follow this approach:

1. Open QuickBooks without any company file.
   
   

2. Go to File → Utilities → Verify Data.
   
   

3. If QuickBooks finds data problems:
   
   

   • Go to File → Utilities → Rebuild Data.
     
     

If you cannot rebuild or the file is severely damaged, contact the data recovery team at 1-888-394-9046 or 1-866-596-1988.

Solution 9: Disable Antivirus or Firewall Temporarily

Security software may block QuickBooks files from opening.

Steps:

1. Turn off real-time antivirus protection.
   
   

2. Allow QuickBooks through your firewall.
   
   

3. Try opening your company file.
   
   

If you don’t know how to configure security settings, call 1-888-394-9046 or 1-866-596-1988 for safe guidance.

Solution 10: Check File Permissions

Insufficient Windows permissions may cause QuickBooks Error 6190.

Verify file access rights:

• Ensure your Windows user account has full control of the folder.
  
  

• Check that the server computer has full read/write rights.
  
  

• Ensure no file is marked as “read-only.”
