What is QuickBooks Error 6190?
QuickBooks Error 6190 is a runtime error that occurs when QuickBooks is unable to open the company file. This issue often appears when another user is already logged into the company file in single-user mode, which blocks access for other users trying to open the file. You may encounter an error message that reads:
"QuickBooks is unable to open this company file. It may have been opened by another user."
This error typically occurs in multi-user mode and prevents you from accessing the company file on a network.
Causes of QuickBooks Error 6190
Several factors could lead to QuickBooks Error 6190. Understanding the root cause can help you resolve the issue more effectively. Here are some common reasons for this error:
1. Mismatch Between the Company File and Transaction Log File
QuickBooks uses both the company file (.qbw) and the transaction log file (.tlg) to store and manage your financial data. If there is a mismatch between these files (e.g., they have different versions or were modified at different times), QuickBooks may not be able to open the company file, leading to Error 6190.
2. Another User is Logged into Single-User Mode
This error often occurs when another user is logged into the company file in single-user mode. When QuickBooks is in single-user mode, only one user can access the file, and any attempt to access the file by another user will trigger Error 6190.
3. Corrupted or Damaged QuickBooks Company File
If the company file or any supporting files become corrupted or damaged, it may prevent QuickBooks from opening the file. Corruption could result from power failures, improper shutdowns, or virus attacks.
4. Network or Server Issues
Network issues, such as unstable connections or misconfigured network settings, can prevent QuickBooks from accessing the company file stored on a server. This could result in QuickBooks Error 6190 when trying to access the file over a network.
5. Incomplete QuickBooks Installation
An incomplete or corrupted QuickBooks installation could also lead to errors. If the software’s installation is not complete or has been corrupted, QuickBooks may not be able to access or open the company file correctly.
Symptoms of QuickBooks Error 6190
Here are some common signs that you may be experiencing QuickBooks Error 6190:
QuickBooks crashes while trying to open the company file.
You are unable to access the company file in multi-user mode.
QuickBooks runs slowly or freezes frequently.
An error message (Error -6190, -816) appears on the screen while accessing the file.
QuickBooks becomes unresponsive or behaves erratically.

2. Rename the .ND and .TLG Files
As mentioned earlier, QuickBooks uses both .ND and .TLG files to manage data and transactions. If these files are corrupted, renaming them can help resolve the error. QuickBooks will automatically create new versions of these files the next time you open the company file.
Here’s how to rename the files:
Navigate to the folder where your QuickBooks company file is stored.
Look for the .ND and .TLG files associated with your company file. They will have the same name as your company file but with extensions like
.NDand.TLG(e.g.,companyfile.qbw.ndandcompanyfile.qbw.tlg).Right-click each of these files and select Rename.
Add the suffix .OLD at the end of the file names (e.g.,
companyfile.qbw.nd.old).Open QuickBooks and try accessing the company file again.
3. Check Multi-User Mode Settings
If the error persists, ensure that QuickBooks is properly configured for multi-user mode. Follow these steps to verify your multi-user settings:
Open QuickBooks on the server that hosts the company file.
Go to the File menu and select Utilities.
If you see an option that says Host Multi-User Access, select it. This will enable multi-user mode on the server.
Make sure the workstations accessing the company file are also configured for multi-user mode.
After enabling multi-user mode, try accessing the company file again.
4. Verify User Permissions
Sometimes, user permission settings may prevent you from accessing the company file in multi-user mode, causing QuickBooks Error 6190. To resolve this, verify that all users have appropriate permissions to access the QuickBooks company file.
Go to the folder where the company file is stored.
Right-click the folder and select Properties.
Under the Security tab, make sure that all users have full control over the folder and its contents.
If necessary, adjust the permission settings and try accessing the company file again.
5. Update QuickBooks to the Latest Version
Using an outdated version of QuickBooks can cause various issues, including Error 6190. Ensure that QuickBooks is updated to the latest release, as updates often include bug fixes and improvements.
Open QuickBooks and go to the Help menu.
Select Update QuickBooks Desktop.
Click on Update Now, and follow the on-screen instructions to install the latest updates.
After updating, restart QuickBooks and try opening the company file again.
