Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
It says that my 5 day pass is officially over when I say I have a product key, but I have a yearly subscription that lasts for a year. Please help
If you have a subscription which is associated with your Microsoft account, use the account to install and activate Office on your PC. Go to https://account.microsoft.com/services . If you have an existing trial version, uninstall that version first.
You can't use the product key more than once (during the initial setup), and if you purchased directly from Microsoft, you usually won't even see a product key at all. The product becomes associated with your account as part of the purchase.
