Licensing

Demo Mode

OpenProtocol Tester runs in demo mode without a license file. In demo mode:

• All features are fully functional initially
• A reminder dialog appears periodically (up to 3 times)
• After the 3rd reminder, some features are disabled until a license is activated

The reminder dialog shows:

• A countdown timer (30 seconds before you can dismiss)
• A Load License File button for immediate activation
• The reminder number (e.g., "Reminder 1 of 3")

Activating a License

Loading a License File

1. When the demo reminder appears, click Load License File... — or at any time, use the menu to load a license
2. Select your .lic license file
3. The application validates the license immediately
4. If valid, demo mode is deactivated and all features are unlocked

The license is stored at:

C:\ProgramData\Haller + Erne GmbH\Licensing\OPTester.lic
