Uninstalled Office 2021 and Installed Office 2024, but still Opens as Office 2021.

It seems that even after uninstalling Office 2021 and installing Office 2024, the applications are still opening as Office 2021. This issue may arise due to residual files or registry entries from the previous installation that are causing the system to reference Office 2021 instead of the newly installed version. Here are a few steps you can take to resolve this:

1. Complete Uninstallation: Ensure that Office 2021 is completely uninstalled. You can use the Control Panel to uninstall it, but sometimes residual files remain. Consider using the Microsoft Support and Recovery Assistant to help remove any leftover files.
2. Check Installed Programs: After uninstalling, check the list of installed applications to ensure that no Office 2021 components are still present. If they are, uninstall them.
3. Registry Clean-Up: If you are comfortable with it, you can check the Windows Registry for any entries related to Office 2021 and remove them. Be cautious when editing the registry, as incorrect changes can affect system stability.
4. Reinstall Office 2024: After ensuring that all remnants of Office 2021 are removed, try reinstalling Office 2024 again. Make sure to download it from a trusted source.
5. Repair Office 2024: If the issue persists, you can try repairing the Office 2024 installation through the Control Panel.

If none of these steps work, it may be helpful to contact Microsoft support for further assistance.
