Solution B: Fixing File Paths

If the data path is incorrect:

  3. Ensure no trailing slashes are missing if required by the specific parser (e.g., C:\Data\ vs C:\Data).

Case Study: The "TecDoc New" VIN Decoder Configuration

One of the most common triggers of this error is the VIN decoding module. TecDoc (New) uses a separate configuration file for the VIN decoder API. If this file points to an outdated or incorrect endpoint, you will see the error even if the main catalog loads partially.

Check the vindecoder.conf section:
Look for a line like: loading data failed check the configuration file tecdoc new

"vinApiUrl": "https://api.tecdoc.net/v5/vin/decode"

If this URL has changed due to a TecDoc version upgrade, you must manually update it. Contact your TecDoc provider for the current endpoint.

If the configuration file is correct but data still fails to load, the cache is likely damaged.

  1. Navigate to the cache directory (check the config file for CachePath; default is often %localappdata%\TecAlliance\TecDoc\Cache).
  2. Delete everything inside the cache folder. Do not delete the folder itself—just the contents.
  3. Launch TecDoc. The system will now force a complete re-download of the catalog data. This may take 10–30 minutes depending on your internet speed. Do not interrupt this process.
