License Error: (Internal: 147 Feature: ATKDFT)

If you are attempting to run a DFT or a Semi-empirical calculation and get the following error:

 License Error: (Internal: 147 Feature: ATKDFT)
 [LOCAL] C:\Users\user\.quantumwise\licenses\license.lic - (Err: 9) Feature not found
 License configuration (environment variables):
 ---------------------------------------------------------------------------
 QUANTUM_LICENSE_PATH = 'C:\\Users\\user\\.quantumwise\\licenses\\license.lic'

it means that this feature is missing from your license file. A common reason is that you are trying to run the DFT calculation with the free VNL license for academics. Notice that the ATK-DFT and the ATK-SE packages are not included in the free VNL license for academics. For that you will need to purchase a license since ATK licenses are not free, only VNL is (for academics). Of course, you can apply for a trial license so you can test these software features for your research.
