Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Hi there,
First, verify that the renewal is active by signing in to your Microsoft account and checking Services & subscriptions. If the subscription is active, close Word and all other Microsoft 365 apps, then reopen Word and sign in with the exact Microsoft account used for the purchase.
If you purchased the renewal through the App Store, “Unable to associate your purchase” can indicate that the purchase is linked to a different Apple/Microsoft account. Sign out of the Microsoft 365 app, close and reopen it, and use Restore Previous Purchase with the account used for the purchase.
If it still does not activate, Microsoft recommends running its Microsoft 365 activation troubleshooter or reinstalling Office after confirming the subscription is active.
Thank you, and feel free to respond back for more assistance.
