I have downloaded Design Expert Trial version, but when running it asks for network license and serial number to activate. What should I do?
The application costs a lot of money. It's impossible to activate it without a valid license. Access the buying page to obtain a license for this product. Additionally, you can test the application by downloading a 45 day trial.
A single user license costs $1095.
