Error Message When Opening a QuickBooks File | Error Code -6129,0

One problem I have had once or twice recently with the same QuickBooks file is that when trying to open it I got an error message box saying Warning! We're Sorry. QuickBooks encountered a problem.

The first time my heart sank and thought oh boy.

My data files are backed up to OneDrive as I go as I store my QuickBooks data files in a OneDrive folder on my local PC so they sync to OneDrive online partly for backup reasons but it is not a true backup!

Why? Well one drive syncs your local files to your online files. So if one is corrupted the sync one will corrupt too.

That is why it is important to also use the create backup file REGULARLY within QuickBooks (I also sync that to OneDrive too for additional backup).

What Fixed the Error -6129,0 For Me?

This is the 2nd time I have had this in a few weeks and for me the solution was to rename the .nd file for that QuickBooks data file.

Open file explorer in Windows navigate to the folder your QuickBooks data files are store in.

Highlight the file name ending .nd then right click on it and select "rename".

Use for example, company file nameofmyqbfile.qbw.nd.OLD

I didn't need to restart QuickBooks just selected the file and hey presto it opens again correctly.

QuickBooks - Intuit Explain The Cause of the -6129,0 Error

The -6129,0 error can be caused by: 

  • Antivirus software causing a problem when creating the new company file
  • A damaged network data file (.nd file extension)
  • Updating a company file from a prior version of QuickBooks when your Windows login is not an Administrator login.
  • Server and client machines not being on the same domain

I wonder whether the OneDrive syncing process can corrupt the .nd files. Although I am storing the QuickBooks data files in a local folder on my computer (not on a network) perhaps the syncing processes to OneDrive corrupts the .nd file maybe when worki ng oin it live or when you close it?

The solution for me has been simple though.

See Intuits advice on the -6129,0 error and other possible solutions.

Hope this helps if you have had this QuickBooks error!

So far no problems with other QB files only the .nd one and the solution for that (so far...) has been very simple each time.
