Solutions To Try When You Open File Locally

When you launch your file locally (on the same computer where you have installed QB), the following solutions will help resolve the QuickBooks error 6129 101:

Technique 1: Rename Network Data and Transaction Log Files

ND and TLG files are configuration files allowing QB to open a company file in a multi-user or network environment. As mentioned in the reasons, the damaged Network Data and TLG files may cause this error, and renaming them can be the solution. Renaming doesn’t cause any data loss. These files get recreated when you scan them through QuickBooks Database Server Manager:

1. Go to the directory where the company file is saved.
2. If not located there, scan the hard drive with all files.
3. Identify the network data file, denoted by the ‘.nd’ extension, and the Transaction Log file with a ‘.tlg’
4. Right-click on these files and tap Rename, adding a different extension like ‘.old.’
5. Restart QuickBooks and try logging into your company file.
6. Should the problem persist, move on to further troubleshooting steps.

Technique 2: Access a Sample Company File

Opening a sample company file helps determine if the problem is with QuickBooks or your company file. When the sample company file throws errors while opening, it suggests a damaged QB installation:

1. Click the Open a Sample File in the No Company Open Choose any sample file from the list.
2. Proceed to the next solution if this file opens. If not, repair your installation files using Quick Fix My Program and QuickBooks Install Diagnostic Tool from the QB Tool Hub. The steps are given below.

4. You must let the tool work, and after the procedure is complete, restart the PC.
5. Launch QuickBooks Desktop and then your data file.

Technique 3: Copy the Company File to the Desktop

Test if your company file location is the problem by copying the file to the desktop and opening it:

1. Your file location may be damaged if the file launches from the desktop.
