Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Alex,
The Office Home LTSC 2024 edition is available only through volume licensing for large organizations. These licenses are often resold illegally by third-party vendors. I recommend contacting the seller directly to request a refund.
If you want to use the Office apps for personal purposes, as Stefan mentioned, you will need to buy the consumer version of Office, such as Home 2024, or subscribe to Office 365.
