Understanding the Error
The "Failed to checkout Chaos license" error indicates that you either do not have access to the Chaos license server, or the license itself is unavailable.
Solutions
1. Check License Server Installation
Ensure that the Chaos license server is installed. If it is running correctly, you should be able to view your licenses by opening an internet browser on the license server computer and navigating to its status page at http://localhost:30304.
2. Verify Online Licensing
If you are using online licensing, ensure you are logged in with the correct Chaos username/email associated with your license. To switch accounts, go to "Online licensing" Deactivate/Sign Out, and then "Online licensing" Enable/Sign In with the correct account.
3. Checking Network Connections
If your Chaos license comes from a server on another computer, ensure that firewalls on both your computer and the license server are not blocking TCP port 30304. Test by entering http://IP_Address:30304 in a browser, where "IP_Address" is the license server's IP. You should be able to see the server's status screen.
4. Adjust License Settings
Ensure your license settings point to the correct server. Use "localhost" or "127.0.0.1" if the server is your local machine.
5. Verify License Availability
If the license is shared, ensure it's not currently being used by others. Visit http://IP_Address:30304 in a browser and check if a free license is available by viewing the engaged licenses.
