Choose your company file from the dropdown.
Click Check your file, then let the scan complete.
This often resolves the mismatch between .TLG and .QBW files.
2. Rename the .ND and .TLG Files
Damaged network descriptor or transaction log files can cause access issues.
To rename them:
Go to your company file folder.
Locate files ending in
.NDand.TLG.Right-click each and rename:
Example:
yourcompany.qbw.nd→yourcompany.qbw.nd.oldExample:
yourcompany.qbw.tlg→yourcompany.qbw.tlg.old
Reopen QuickBooks and try accessing the file.
3. Ensure Only One System is Hosting the File
QuickBooks should only be hosted by one computer on the network.
Steps:
On each system, open QuickBooks and go to File > Utilities.
If you see Stop Hosting Multi-User Access, select it (only on systems that are not the main host).
Ensure the host system is the only one with hosting enabled.
4. Update QuickBooks Desktop
Running older versions of QuickBooks can cause compatibility issues.
To update:
Open QuickBooks and go to Help > Update QuickBooks Desktop.
Click Update Now and then Get Updates.
Restart QuickBooks after the update completes.
Keeping QuickBooks up to date also prevents future file and sync errors.
5. Sync File Versions Across All Systems
If your company file was copied or opened from another computer, the local versions might not match.
Ensure everyone is accessing the same file from the same location.
Avoid copying files manually between systems.
Always close QuickBooks properly to avoid locking the file.
