How to Resolve QuickBooks Error 6190 816

Encountering errors while using accounting software can disrupt your business processes and cause undue stress. One such vexing issue is the QuickBooks Error 6190 816. 

What is QuickBooks Error 6190 816?

QuickBooks Error 6190 816 is a common technical glitch users may face while opening their company files. The error usually comes with a message stating, “QuickBooks was unable to open the file [path] on the host computer.” This error indicates that QuickBooks cannot access the company file due to a mismatch between the transaction log file (.tlg) and the company file (.qbw).

Understanding the File Extensions:

  • .QBW: This is the main QuickBooks company file.
  • .TLG: A transaction log file that automatically records all transactions entered into the company file.

Common Causes of QuickBooks Error 6190 816

To effectively troubleshoot any error, understanding its root causes is crucial. Here are the common reasons why Error 6190 816 might occur:

  1. Mismatch Between .QBW and .TLG Files: This is the primary cause where the .QBW file does not match its corresponding .TLG file.
  2. Company File in Single User Mode: If another user is accessing the company file in Single User mode, you might face this error when attempting to access it simultaneously.
  3. Data Corruption: The data file can prevent it from opening correctly.
  4. Update Errors: Updating a file on a different computer without updating the transaction file can lead to discrepancies.
  5. Network Issues: Errors in network configuration or issues with the network connection can also trigger this error.

Troubleshooting Methods to Resolve QuickBooks Error 6190 816
