Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Hi, Aimee Earl
Office Home & Student 2016 is a one-time purchase, but activation on a new laptop can still fail if the new PC has a preloaded Microsoft 365 trial, more than one Office version installed, or if the copy came from a school/work discount or laptop bundle instead of a normal retail purchase. Office 2016 is also out of support now.
Here are some suggestions you can try:
Uninstall any preinstalled Microsoft 365 trial or extra Office versions on the new laptop, restart, then open Word or Excel again. Multiple installs can cause activation conflicts.
Also check that the laptop’s date, time, and time zone are correct, then try opening an Office app once as administrator.
If the key was bought separately and now shows invalid, it is suggested that you contact the seller.
Thank you for your patience in reading, I hope this information has been helpful to you.
