TecDOC releases regular updates. If you have ignored update prompts for several months, the backend servers may have deprecated an old API version. Your configuration file still points to the old endpoint, but the server rejects the handshake. The error message is a catch-all: “Check your config” (because your config is outdated).
Make sure you are initializing the client correctly, e.g. in C#:
var config = new TecDocConfiguration
ApiUrl = "https://webservice.tecdoc.net/...",
Username = "your_username",
Password = "your_password"
;
If you see the “new” mention, perhaps you are using a new version of TecDoc API (TecDoc Web Services v5 or v6) — ensure your configuration matches the updated endpoints and authentication method (e.g., from Basic Auth to Token-based).
The configuration file contains critical settings: API endpoints, local cache paths, language settings, and license keys. If this file becomes corrupted—due to an improper shutdown, a failed Windows update, or a disk write error—TecDOC New cannot parse it. The application reads garbage data, panics, and throws the error.
Before we fix the problem, we need to understand the architecture of TecDOC New. Unlike a standard website, TecDOC New is a hybrid application. It runs locally on your Windows machine (using a web server shell) but pulls live data from TecDOC’s central servers via APIs.
When you see “Loading Data Failed”, the software is telling you that it successfully launched the user interface, but it cannot fetch the necessary data (vehicle makes, models, parts, or your subscription status) to populate that interface.
The second part of the error—“Check the Configuration File”—is the software’s way of pointing a finger at the instruction manual it uses to find the data. That instruction manual is a configuration file (usually a .json, .xml, or .ini file stored locally on your hard drive).
In short: The software is running, but it has lost the map to the data warehouse.
The error "Loading data failed check the configuration file tecdoc new" indicates a breakdown in the link between the application interface and the database or data files. In 90% of cases, this is resolved by correcting the file pathing or database connection strings within the configuration file. By systematically verifying the database status, file permissions, and syntax validity, service can be restored rapidly.

The "Loading data failed: check the configuration file" error in TecDoc usually indicates that the application cannot establish a connection to its database or the configuration file itself is corrupted or missing. Step-By-Step Troubleshooting Guide 1. Verify Database Connectivity loading data failed check the configuration file tecdoc new
The most common cause is a failed connection to the PostgreSQL or MS SQL database where the TecDoc data is stored.
Check Service Status: Ensure that the database service (e.g., postgresql-x64-xx) is running in the Windows Services manager (services.msc).
Credentials: Verify that the database username, password, and port matches what is defined in the configuration file. 2. Locate and Fix the Configuration File
TecDoc relies on specific XML or properties files to load its environment.
File Location: Look for a file named config.xml, tecdoc.properties, or similar within the installation directory (typically C:\Program Files\TecDoc\). Common Issues:
Invalid XML: If the file was manually edited, a single missing bracket can cause the load to fail.
Path Errors: Ensure the dataPath or databasePath points to the actual location of the data files.
Restore from Backup: If you have a .bak or .old version of the file, try renaming it to the original name and restarting the application. 3. Check for Permissions and Path Issues
Run as Administrator: Right-click the TecDoc executable and select Run as administrator to ensure it has permission to read the configuration file.
Corrupted Registry: If you recently updated, some registry paths might still point to the old version's data. Consider exporting a backup of your registry before making manual path changes. 4. Address "TecDoc NEW" Specifics (IDP/Web Services) TecDOC releases regular updates
If you are using the newer Instant Data Processing (IDP) or web-based catalog:
API Connection: Check your internet connection and API keys. The "configuration" may refer to your TecAlliance Login credentials.
Scheduled Downtime: Verify if there is ongoing maintenance on the TecAlliance Status Page. Still not working? If these steps don't resolve the issue, you may need to:
Reinstall the Client: Perform a clean install but back up your license files first.
Contact Support: Reach out to TecAlliance Support with your specific error logs. I can help further if you tell me:
Are you using the Offline Desktop version or the Online API?
Have you recently updated the software or moved the data to a new drive?
Can you share the exact file name or folder path you found in the error message?
The error message "Loading data failed, check the configuration file" in TecDoc (specifically the "new" or Catalog versions) typically indicates that the software cannot find or read its database connection settings. Common Solutions
Check the Configuration File: Locate the config.xml or tecdoc.ini file in the installation directory. Ensure the path to the database (SQL Server or local files) is correct. If you see the “new” mention, perhaps you
Verify Database Services: If you are using a network or SQL version, ensure the SQL Server (TECDOC) service is running in your Windows Services (services.msc).
Run as Administrator: Right-click the TecDoc shortcut and select Run as Administrator to ensure the program has permission to read the configuration and data files.
Firewall/Antivirus: Check if your security software is blocking the connection to the data source.
Configuration XML Mismatch: For certain versions, this occurs if a wc-loader-businessobject.xml is used instead of a wc-dataload.xml during setup.
For specific troubleshooting based on your license or portal access, you can refer to the TecAlliance Error List or contact their support if you lack administrative access.
The "Loading data failed, check the configuration file" error in TecDoc often arises from misconfigured file paths in the config.ini
file or a failure to connect to the SQL database. It is typically resolved by verifying database service status, running the Data Load Utility as an administrator, or ensuring adequate free drive space.

TecDOC New requires at least 5GB of free space for cache and logs. Set up a disk cleanup schedule. A full hard drive corrupts cache files silently.
