How to update Document Reader SDK database?

This guide explains how to update the Regula Document Reader SDK template database to ensure support for new documents and improved recognition capabilities. The database can be updated automatically via the internet or manually using downloaded files.

Requirements

• A Regula Document Reader device connected to your workstation.
• Access to the Document Reader application settings.
• Internet connection (required for automatic updates).
• Administrator privileges to modify application directories.

Required Actions

Automatic Update via Internet

1. Enable auto-update in settings:
   • Open the Document Reader application.
   • Navigate to Settings → General.
   • Turn on Check for updates to enable automatic checks.

     

   • Optional: Enable Allow silent DB update for auto-update without user notification.

    

2. Restart the application. The system will download and install updates automatically if available.

Manual Update via .dat File

1. Download the database file:
   • Select the appropriate architecture:
     • x86 version for 32-bit systems.
     • x64 version for 64-bit systems.
   • Choose the .dat file from the download page.
2. Prepare the file:
   • Copy the downloaded .dat file to the update folder: C:\Users\<USER>\AppData\Local\Regula\Document Reader SDK\Updates\data.
   • Rename the file to data.dat (replace existing file).
3. Clean previous versions:
   • Delete the C:\Users\<USER>\AppData\Local\Regula\Document Reader SDK\Updates\bin folder.
4. Restart the Document Reader application to apply changes.

Verification

The update is successful if:

• Automatic update: A confirmation message appears in the application.
• Manual update: The application launches without errors and uses the new database version.

Common Issues and Solutions

• No internet connection during auto-update: Use manual update steps described above.
• File not recognized during manual update:
  • Ensure the file is renamed to data.dat.
  • Verify the file is placed in the correct data folder.
