When PADS4 is initially installed, activation is completed using the PADS4 License Wizard. This process generates a hardware-bound product key, which is verified against your system’s hardware profile.

​
Graceful Degradation Period: 7 Days

If hardware changes are detected (e.g., replacement of the network adapter or changes in system identifiers), PADS4 enters a graceful degradation period.
  • Duration: 7 days
  • During this time, the system continues to function normally
  • A warning message is displayed during login for the following applications:
    • PADS4 Agent
    • PADS4 Messenger
    • System Management
    • Scheduler
    • Designer
You can configure an alert within the PADS4 Agent to notify administrators via email when hardware changes are detected and reactivation is required.

​
Reactivating the PADS4 Server

To prevent PADS4 from shutting down after the 7-day grace period, follow these steps:

​
Step-by-Step Reactivation Process:

  1. Contact your reseller to report the hardware change and request reactivation.
    • Provide your PADS4 product key.
  2. The reseller will contact Net Display Systems to verify your license and authorize reactivation.
  3. You will receive an email confirmation once your license has been approved for reactivation.

​
Reactivation via License Wizard:

  1. Launch the License Wizard on the PADS4 Server.
  2. Select the Server and click Next.
  3. Review the current license details and click Next again.
  4. In the Select an Action window, choose:
    • Reactivate current installation
  5. The wizard will connect to the PADS4 License Server to verify your key.
  6. Upon successful validation, the hardware profile is reset, and the degradation period ends.
Note: An internet connection is required for online reactivation.

​
Offline Activation:

If your server does not have internet access:
  • Select Activate installation offline in the License Wizard
  • Follow the guided instructions to complete activation manually

Best Practices and Recommendations

  • PADS4 will stop working after 7 days if the reactivation is not completed.
  • If running on a virtual machine, ensure the MAC address is fixed to avoid unintended hardware changes.
  • Avoid enabling or sharing Bluetooth devices on virtual machines, as this may trigger a hardware change detection.
  • Use email alerts via the PADS4 Agent to stay informed about pending reactivation requirements.

​
What Triggers a Hardware Change Detection?

PADS4 compares several hardware identifiers to the original activation data. If any of the following change, a reactivation may be required:
  • Operating System
  • Processor ID
  • OS Installation Date
  • OS Serial Number
  • BIOS Serial Number and Version
  • Network Adapter and MAC Address
  • Windows Activation Code
