Navigate to the official Microsoft Support contact page in your web browser.
Log in using the exact Microsoft account associated with your Office 2024 one-time purchase.
Describe your issue, choose 'Office' as the product, and select the 'Licensing and Activation' category from the dropdown menus.
Choose the option to chat with a support agent or request a telephone callback to have them securely verify and reactivate your purchase.

Frequently Asked Questions
Why did my Office 2024 license disappear after a macOS update?
Major macOS updates, like macOS Sequoia, can sometimes reset hardware identifiers or modify core system files that Microsoft Office uses to verify its local license, causing it to incorrectly display a 'No License Found' error.
Can I reactivate my Office 2024 one-time purchase myself?
If signing out and signing back into your Microsoft account within the Office app does not restore the license, you must contact Microsoft Support directly. The one-time purchase might need to be manually unlinked from the previous operating system state.
How do I check which Microsoft account is linked to my Office 2024 license?
Go to account.microsoft.com, log in, and navigate to the 'Services & subscriptions' section. This page will list all Office purchases and licenses permanently linked to your account.
Does WPS Office require a paid license to open my existing Microsoft files?
No, WPS Office offers a robust free tier that allows you to open, edit, and save standard Microsoft Office formats without needing a paid license or struggling with a complex activation process.
