This is NOT helpful! I have a valid Microsoft product key for Office 2021 but the ONLY link provided takes me to the Office365 website and that is NOT what I purchased. There is no way to actually download Office 2021. Why is this?

My father recently gave me a microsoft office 2021 professional plus product key however when going through the setup process at office.com/setup multiple times it says service unavailable, i also tried it in the default microsoft office but it says something about volume version and i can't use the product key on that.

Any other alternative to getting an office 2021?

Hi, thank you for responding!

I'm looking at www.office.com, but I don't see that install button you mentioned.

As for the button "Install apps", it doesn't let me download Office 2021, but instead gives me these options.

Is there another button I'm supposed to use?

Hello HP P,

Welcome to Microsoft Community.

I am a Microsoft user just like you, I hope you are doing well.

Sorry for the inconvenience. First, I will like you to verify that this Office 2021 license is associated with your Microsoft account.

Go to the Manage Subscription page (https://account.microsoft.com/services) and confirm that your Office 2021 license is associated with your Microsoft account.

Once confirmed, I will suggest you completely uninstall Office from your PC using the Uninstall support tool, then, try installing Office 2021.

To uninstall Office completely use the uninstall support tool

  1. Download the Office uninstall support tool.

https://aka.ms/SaRA-officeUninstallFromPC

  1. Open the download on your browser, and when you're prompted in the Application Install window, select Install, and then I agree for the Microsoft Services Agreement. Run the file after downloading.
  2. From the Uninstall Office products window, select the version of Office you want to uninstall, and then select Next.
  3. Follow the prompts on the remaining screens and when prompted, restart your computer. After you restart your computer, the uninstall tool automatically re-opens to complete the final step of the uninstall process. Follow the remaining prompts.

Find link attached from Microsoft on how to uninstall Office a PC:

https://support.microsoft.com/office/9dd49b83-264a-477a-8fcc-2fdf5dbf61d8

To install Office 2021 on new PC:

  1. Go to www.office.com and if you're not already signed in, select Sign in.
  2. From the Office home page select Install Office.
  3. Select Install (or depending on your version, Install Office>).
  4. This completes the download of Office to your device. You can now proceed to install Office 2021.
  5. Once you're done installing Office 2021, you can then sign in your Microsoft account associated with this license to activate Office apps.
