    Try these steps in order:

    1. Check whether Teams works in a browser first.
      • Open the web version: https://teams.microsoft.com/
      • If the desktop app is blocked or broken, this confirms the account can still access Teams while the app issue is being fixed.
    2. Sign out of Teams completely and restart it.
      • In Teams, select the profile picture at the top right.
      • Select Sign out.
      • Close Teams, reopen it, and sign in again.
    3. Clear the Teams cache on the laptop.
      • This removes local app data that can cause reinstall or startup failures.
      • On Windows:
        1. Right-click the Teams icon in the taskbar and select Quit.
        2. Open File Explorer.
        3. Paste this path: %appdata%\Microsoft\Teams
        4. Delete the contents of that folder.
        5. Restart Teams and sign in again.
      • Note: clearing the cache does not remove Teams, but it does remove local cache items such as thumbnails, icons, local message history, display images, and add-ons.
    4. If Teams still will not install or reload, uninstall and reinstall it.
      • Reinstalling can fix a corrupted local installation or incomplete update state.
    5. If the install error mentions organization policy, check Windows app-install restrictions.
      • The new Teams installation can be blocked by these registry-controlled settings:
        • BlockNonAdminUserInstall
        • AllowAllTrustedApps
        • AllowDevelopmentWithoutDevLicense
      • These are found under:
        • Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\AppModelUnlock
        • Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\Appx
      • Important: changing registry or policy settings can affect app installation behavior across the device. Use caution.
    6. Update Windows if installation keeps failing.
      • A known issue where AllowAllTrustedApps being disabled blocks new Teams MSIX installation was fixed in later Windows updates.
      • Install the latest available Windows updates, then try the Teams install again.
    7. If the laptop is on Windows 10 and the installer shows a WebView2-related error, install WebView2 Runtime, then restart Teams and try again.

    If the device is managed by a school or organization and the error says Due to org policy, you can't install the new Teams, the install is being blocked by device policy and requires an IT admin to change that setting.

    Dear @Lou Hudyman

    I understand how frustrating it can be when Microsoft Teams gets removed and won't reinstall due to installation errors. I can help you resolve this so you can get back to work quickly.

    This error usually happens because left-over cache files or registry fragments from the previous installation are blocking the new installer.

    Please follow these steps to perform a clean reinstallation:

    Step 1: Use the Web Version (Immediate Workaround)

    If you need immediate access to your meetings or chats, you can sign in to the Microsoft Teams Web App using any modern browser: https://teams.microsoft.com
    Step 2: Clear Corrupted Teams Cache

    • Press Windows Key + R to open the Run dialog box.
    • Paste the following path and press Enter: %userprofile%\appdata\local\Packages\MSTeams_8wekyb3d8bbwe\LocalCache\Microsoft\MSTeams
    • Select and delete all files and folders inside this folder. (Note: This will not delete your personal chat history or files; it only clears temporary data).

    Please refer to this document: Clear the Teams client cache
    Step 3: Reset App Settings via Windows

    • Open Windows Settings (Win + I) > Apps > Installed apps.
    • Search for Microsoft Teams in the list.
    • Click the three dots next to it and choose Advanced options.
    • Scroll down and click Repair. If the installation error persists, return here and click Reset.

    Please refer to this document: Repair an Office application

    Step 4: Download and Reinstall Official Teams

    • Restart your computer.
    • Download the official, latest installer directly from Microsoft: Download Microsoft Teams Desktop App
    • Right-click the downloaded file and select Run as administrator.

    For detailed troubleshooting on new Teams installation errors, you can refer to the official Microsoft Teams Learn Documentation.

    Please try these steps and let me know if you encounter a specific error code during installation so I can assist you further.
