Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
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!
