Node-locked licenses bind strictly to your system's hardware configuration.
If you have admin rights to the license server:
: Run qnxactivate.exe from the new location to re-establish the license link. 3. Complete Registration and Activation

Many QCC licenses are "node-locked," meaning they are tied to the unique hardware ID (MAC address) of your machine. If you’ve switched computers, changed network cards, or are using a virtual machine with a dynamic MAC address, the check will fail.
: Check your home directory for hidden license files (e.g., .qt-license or QNX-specific equivalents) and move them to a backup location before re-running the activation tool.
To resolve QCC license check failures, try the following solutions: Node-locked licenses bind strictly to your system's hardware
The background service responsible for license monitoring (like FlexLM or a proprietary QCC service) isn't running. How to Fix the Error 1. Restart the License Service
Ensure the path points to the correct server address (e.g., 27000@server_name ) or the correct local folder. 4. Delete Cache Files
If you have exhausted all other options, your last and most effective step is to contact the software vendor's official technical support. For QNX, you can contact corp-activate@qnx.com for activation issues, providing your myQNX email and product serial number. For Qualcomm, developers with a valid license agreement can access support through Qualcomm's mysupport.qualcomm.com portal. When doing so, be sure to include all relevant error messages and the steps you have already taken to resolve the issue. Complete Registration and Activation | Solution | Action
If you generated the license while connected to a docking station or Ethernet, switching to Wi-Fi or turning on a corporate VPN can mask the primary MAC address, causing the check to fail. Disable your VPN or switch back to the original network adapter to test. 4. Restart the FlexNet / License Server Daemon
Some discussions of "license check failed" are also found for other tools, such as (a static code analysis tool). Here, the error can indicate a firewall blocking the required port. The solution involves adding a firewall rule for the specific port (e.g., 8080) for the Validate component of the software. If you are using code analysis tools, be sure to verify your context and check their respective documentation.
The system cannot find the path to the license file ( .lic ).
