Understanding QuickBooks Error 6190

QuickBooks Error 6190 belongs to the 6000 series of errors, which are generally related to file access or company file corruption. This error typically appears with the message:

“QuickBooks is unable to open this company file. It may have been opened by another user…”

This happens most frequently in multi-user mode environments or when there’s a file discrepancy.

What Triggers QuickBooks Error 6190?

There are several potential causes, and understanding them is key to applying the right fix.

1. Mismatch Between .QBW and .TLG Files

When the company file (.QBW) and its transaction log file (.TLG) are not in sync, QuickBooks throws this error.

2. File Is Open in Single-User Mode

If one user has the company file open in single-user mode, other users can’t access it.

3. Network Issues or Hosting Misconfigurations

In a multi-user setup, improper host settings on the server can block access to files.

4. File Corruption or Damage

Damaged data files or improper shutdowns can lead to corruption that triggers error 6190.

5. Outdated QuickBooks Version

If your QuickBooks software isn’t up to date across all devices, compatibility issues may result in access errors.
