If you do not have an Internet connection, or require a floating or counted license installation, choose Advanced Activation and click Next; there will be two options to choose from:
- I want to use another computer with internet access to activate my license.
Choosing this option will take you through four steps for "Remote Activation."
- I want to use a license file to activate my software.
