If you need to install a Microsoft application on a standalone system without an Internet connection, the possible method to validate it is:
A. Use the telephone validation method
Explanation:
1. The telephone validation method involves calling a toll-free number provided by Microsoft during the installation process.
2. When you call the number, an automated system will guide you through the validation process.
3. You will be asked to input a series of numbers displayed on your screen to validate your installation.
4. Once validated, the Microsoft application will be activated and ready to use on your standalone system without requiring an internet connection.
Using the telephone validation method is a reliable way to authenticate and activate Microsoft applications when an internet connection is not available. It ensures that you can still use the software legally and without any interruptions.
