    There is currently a world-wide issue with several Microsoft services which may be a factor here. See https://status.cloud.microsoft/ .

    Install Office 2021 with the offline installer; if error 0-2015 (2250) persists, remove the existing Office components with Microsoft’s uninstall troubleshooter, restart Windows, and reinstall.

    1. Try the Office 2021 offline installer

    This avoids problems that can occur while the web installer is downloading installation files. A matching Office 2021 installation case was resolved using the offline installation method.^1^

    1. Confirm that the Windows system drive—normally C:—has sufficient free space.
    2. Sign in to the Microsoft account dashboard using the account associated with Office 2021.
    3. Select Office apps, locate Office 2021, and select Install.^2^
    4. In the installation window, select Offline installer under Choose a version, choose the language, and select Install.
    5. After the .img file downloads, double-click it to mount it as a virtual drive.
    6. Open that drive in File Explorer, open the Office folder, and run:
      • Setup64.exe for 64-bit Office, or
      • Setup32.exe for 32-bit Office.
    7. When installation completes, reconnect to the internet, open Word or Excel, and sign in to activate Office.

    Microsoft documents the mounting and Setup32.exe/Setup64.exe process for the offline installer.^3^

    2. If the same error returns, completely remove Office

    A previous or incomplete Office installation can interfere with the new installation. Use Microsoft’s automated removal process rather than deleting Office folders manually.

    1. Open Microsoft’s Uninstall Microsoft 365 or Office from a PC page.
    2. Under Uninstall Microsoft 365 or Office with the uninstall troubleshooter, start the troubleshooter.
    3. If the browser displays This site is trying to open Get Help, select Open.
    4. Choose the installed Office product and complete the removal prompts.
    5. Restart the PC when prompted—not merely shut it down and turn it back on.
    6. Mount the offline installer again and run the appropriate setup file.

    The troubleshooter supports Office 2021 and must be run on the affected PC with Windows 10 or later.^4^

    3. Check the product type if installation still fails

    The installation method must match the license:

    • Retail Office 2021: install from the Microsoft account associated with the redeemed product key.
    • Office LTSC 2021 or another volume-license edition: do not use the retail installer. LTSC installation requires the appropriate Office Deployment Tool configuration.
    • Office preinstalled without a product key or Microsoft-account activation: reinstall it from Microsoft Store → Library → Apps/All → Office → Cloud button.^5^

    Avoid registry deletion unless Microsoft Support identifies a specific leftover configuration. Manual Office removal is complex, requires administrator privileges, and can damage Windows if performed incorrectly.^6^
