365 overwriting office 2024 activation credentials

hi terencesumpter​  It sounds like the Office repair may have changed or removed the activation information for your Office 2024 installation, and Office is now detecting Microsoft 365 instead.

Since the PC came with Office 2024 pre-installed, the first thing I'd check is Settings → Apps → Installed apps and confirm which Office version is actually installed. Look for Office 2024 rather than a Microsoft 365 installation.

If Office 2024 is still installed, open Word and go to File → Account and check what product is listed under Product Information. The important part is whether it says Office 2024 or Microsoft 365.

If it shows Microsoft 365 and you never had a subscription, the online repair may have installed/reconfigured the Microsoft 365 version. In that case, you may need to reinstall the Office 2024 edition that came with the PC.

Because it was pre-installed, the activation may be associated with the manufacturer's digital license or the Microsoft account used when Office was originally activated, rather than a physical product key.

I wouldn't start a Microsoft 365 trial just to get past the message, as that could make the activation situation even more confusing. If you can share the exact Product Information shown in Word → File → Account, it should help determine which Office installation is currently active.
