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
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)
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.
