Troubleshooting "Loading Data Failed": Fixing Your TecDoc Configuration
If you’re working with the TecDoc catalog—the gold standard for vehicle parts data—you’ve likely encountered the dreaded error: "Loading data failed. Check the configuration file."
It’s frustrating, especially when you have a deadline or a shop waiting for parts info. The good news? This is almost always a communication breakdown between the software and its settings. Here is how to fix it. 1. The Usual Suspect: The config.ini
Most TecDoc integrations rely on a specific configuration file to tell the system where the database lives. Locate the file: Look for files named config.ini settings.json in your root directory. Check the Path: Ensure the DatabasePath ServerAddress
is pointing to the correct location. If you moved your folders recently, the software is still looking for the "old home." 2. Database Connection Strings loading data failed check the configuration file tecdoc work
If you are using a SQL-based version of TecDoc, the "Loading Data Failed" message often means the login credentials expired or changed. Verify User/Pass:

Windows Updates or new Antivirus software can sometimes block TecDoc from reading its own config file. Run as Admin: Right-click the config file → Properties → Security
Try right-clicking your TecDoc application and selecting "Run as Administrator."
Ensure your firewall isn't blocking the port (usually 3000, 8080, or SQL ports) that the data uses to "load." 5. Data Version Mismatch
If you recently downloaded a new data update but didn't update the configuration file to reflect the new folder name (e.g., changing from
), the system will fail. Always ensure the folder names in your directory match the strings in your config file exactly. Still stuck? Most of the time, a simple restart of the database service followed by a quick check of the file paths in your config file solves 90% of these errors. Are you running a local standalone installation API-based integration or contains the wrong directions.
? Knowing this can help narrow down the specific file you need to edit.
Even if the config file is correct, TecDoc may not have permission to read it.
Fix:
SYSTEM, Administrators, and your user have at least Read & Execute.Always update the TecDoc client software before or alongside a major data version upgrade. Mixing versions is a recipe for configuration mismatch.

If you get "Access Denied" or the file is missing, proceed to permissions (Step 6)."Loading data failed check the configuration file" means the application successfully launched, but when it tried to pull vehicle or part data, it hit a wall. The system is telling you that the "road map" (configuration file) pointing to the data is either missing, unreadable, or contains the wrong directions.
