Office 2024 Included with Laptop but Displays License Warning

Hi everyone,

My mother is a kindergarten teacher, and her school recently received a laptop that came with Office Home & Business 2024 included.

The laptop had previously been used by another teacher. She was apparently unaware that Office was already included and may have installed a different copy of Office instead. The installation was very slow and may not have been a genuine version.

We are now trying to use the included Office license, but we keep getting a message stating that the license is not genuine.

To rule out any issues caused by previously installed software, we performed a complete Windows reinstallation. Unfortunately, the problem persists.

On the Office account/help page, the product appears as activated. However, on the main Office page, there is still a banner at the top indicating that the license is not genuine.

The installation was downloaded directly from the Microsoft Store. I have also tried uninstalling and reinstalling Office, but the result is the same.

Could anyone please advise what might be causing this issue and what steps we can take to resolve it?

I have attached a couple of screenshots (in Ukrainian) that should help illustrate the problem.

Thank you in advance for your help.
