I got a new computer. I deleted Office 2021 from the old one, but now when I try to install Office 2021 on the new one all I get is Office 365. I do NOT want 365. How do I fix this?

    It's a little embarrassing, actually. (Chalk it up to a lack of sleep over the Holidays.)
    I was looking for a folder that had all of Office 2021 in it. I finally looked for each individual program and found each separately.
    I still don't want Office 365, but I suspect I will simply delete it from this computer.

    Hii,

    Do you have an active Office365 or Microsoft 365 subscription?

    Offline Office 2021 installation: https://officecdn.microsoft.com/db/492350F6-3A01-4F97-B9C0-C7C6DDF67D60/media/en-US/HomeBusiness2021Retail.img

    Once the download is complete, disconnect from your computer. Reconnect to the Internet, right-click and select "Mount." Open File Explorer > My Computer > Office icon > right-click and select "Open." > Office folder > Run the setup64.exe file.

    Give feedback if the information was useful or not.

    Thanks

    To reinstall Office 2021 on your new computer, follow these steps:

    1. Sign in to your Microsoft account: Go to the Microsoft account portal where you purchased Office 2021. Ensure you are logged in with the same account that you used to buy Office 2021.
    2. Download Office 2021: Once signed in, navigate to the services & subscriptions section. You should see Office 2021 listed there. Click on the install button to download the installer for Office 2021.
    3. Install Office 2021: After the download is complete, open the installer and follow the on-screen instructions to install Office 2021 on your new computer.

    If you are still being directed to install Office 365 instead of Office 2021, make sure that you are selecting the correct product during the installation process. If necessary, you may need to uninstall any previous Office installations or use the Microsoft Support and Recovery Assistant tool to help with the installation process.
