What Causes the "QuickBooks Already Has a Company File Open" Error?

QuickBooks Desktop is a powerful application, however; it relies on rules of file-management. A breach of any of these rules can be interpreted as a second file being open when closed, even though this is not the case. The most frequently occurring triggers are:

1. Multi-User Mode Misbehavior.

When the QuickBooks does not switch to the Multi-User mode correctly when it leaves the Single-User mode, then the software is likely to lock the company file that was already opened.

2. Background Processes are still Running.

There is a possibility that the QuickBooks process (QBW32.exe) will still be running even after you have closed the program and this causes QuickBooks to believe that the file is still open.

3. Hosting Misconfiguration

When a hosting is enabled to serve more than one workstation, then QuickBooks can assume that there are more than one active file session.

4. Broke or Competent QBW.TLG or ND Files.

The support files that are being used to monitor the connections may become corrupt causing QuickBooks to think that the file is being used.

5. Windows Restrictions or File Permissions.

Little user permission may make QuickBooks malfunction and the program may presupose the existence of a file.
