What is QuickBooks Error 6190?

QuickBooks Error 6190 is a runtime error that typically occurs when QuickBooks is unable to open the company file. This error is often accompanied by the message:

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

This error can be frustrating, especially during critical financial operations, but understanding its causes and solutions can help you get back on track quickly.

Causes of QuickBooks Error 6190

Several factors can trigger QuickBooks Error 6190. Identifying the root cause is crucial for effectively resolving the issue. Here are some common reasons:

1. Mismatch Between Transaction Log and Company File

A mismatch between the transaction log file (.tlg) and the company file (.qbw) can cause Error 6190. This usually happens when a company file is updated on a different computer without updating the transaction log file.

2. File Corruption

Corruption in the company file or the transaction log file can lead to Error 6190. This corruption can occur due to improper system shutdowns, malware attacks, or other technical glitches.

3. Single-User Mode

If another user is logged into the company file in single-user mode, it can prevent other users from accessing the file, resulting in Error 6190.

4. Network Issues

Network connectivity issues between the host computer and other systems on the network can also trigger this error.

Identifying QuickBooks Error 6190

Before diving into solutions, it's important to confirm that you are indeed facing Error 6190. Here are some steps to identify the error:

Check the Error Message

When you attempt to open the company file, you will likely receive a message stating that QuickBooks is unable to open the company file, which indicates Error 6190.

Verify the Error Code

QuickBooks displays an error code along with the error message. Look for Error Code 6190 in the error message to confirm the issue.
