QuickBooks Error 6000 is a common issue that arises when users try to open a company file, and QuickBooks cannot access it. This error is part of the 6000 series and often includes additional codes like 6000, -83 or 6000, -77, which indicate specific problems with file location, network setup, or file corruption.

Common Causes:​

1. Damaged company file (.QBW)
2. Incorrect file permissions or folder location

4. These files will be recreated automatically when you reopen the file.

3. Check Hosting Settings:

1. On every computer running QuickBooks:
   • Open QuickBooks, go to File > Utilities.
   • If you see Stop Hosting Multi-User Access, click it.
   • Ensure only the server hosts the file.

4. Move the File to a Local or New Folder:

1. Copy the company file to your local desktop.
2. Open QuickBooks and try accessing it from the new location.
3. If it opens, there might be issues with your network or folder permissions.
