Troubleshooting: Primary locking code is missing

📌 Problem

Trying to deactivate your Applanix POSPac licenses in the Applanix Software License Utility (SLU) fails with the error, "Primary locking code <LOCKING CODE> is missing! Please restore it before revoking."

🔍 Root Cause

This means POSPac cannot deactivate the license because the primary locking code (hardware ID) that was originally used to activate the license is no longer present. This usually happens if:

• The hardware configuration changed (e.g., hard drive replaced, network adapter disabled).
• The license was tied to a specific device component that is now missing or disabled.

✅ Probable Resolutions

1. Check Hardware Changes
   • Ensure the original hardware (e.g., network adapter or USB dongle) used for activation is still connected and enabled.
   • If you recently changed hardware or disabled a network adapter, re-enable it.
2. Restore Locking Code
   • Go to Applanix Software License Utility → Locking Code section.
   • Verify if the missing locking code can be restored by reconnecting the original hardware.
3. If You Cannot Restore It
   • Contact Support with the "log.txt" file from “C:\Program Files (x86)\Applanix\SoftwareLicenseUtility” folder.
4. Prevent Future Issues
   • Before deactivating, always ensure the hardware tied to the license is active.
   • If you plan to change hardware, deactivate the license first.
