    Hello,

    The Installation ID isn't printed on a card or in an email, it is generated by your laptop during the phone activation process.

    Open an Office app like Word and when the activation wizard appears, select the option labeled I want to activate the software by telephone and click Next. You should see the Installation ID displayed on that screen, usually grouped into several blocks of numbers.

    Let me know how it goes!

    To find the installation ID for your Microsoft Office 2021, you need to follow these steps:

    1. Open the Activation Window: When you attempt to activate Office, it should prompt you for the installation ID.
    2. Get the Installation ID: The installation ID is a 36-digit number that you will see in the activation window. It is typically displayed in groups of six numbers.
    3. Using the Command Line: If you do not see the installation ID, you can also run the command cscript ospp.vbs /dinstid in the command prompt to display the Installation ID for offline activation. This script is located in the Office installation directory, usually found in C:\Program Files\Microsoft Office\Office16 (for Office 2016 and later versions).

    Once you have the installation ID, you can proceed with the activation process by following the prompts provided in the activation window.

    If you need further assistance, please refer to the official Microsoft documentation for more detailed instructions on activating Office products.
