Dewesoft not registered wit C++ script

Hello , i am not able to use C++ scrip , Getting message Dewesoft not registered wit C++ script . How to solve this

Dear Pulappadi,

thank you for contacting us. The current license that you are using does not include the C++ Script option. If you would like to test the C++ Script you could use the Evaluation license which can be created on our web page.

For more information about the C++ Script licensing please look at our forum solution or the manual C++ Script manual.

Kind regards.
