# Solution: Office Apps Close Immediately After Launch

If you open Word, Excel, Outlook, or another Office app and it closes right away (with no clear error message), this is a fairly common issue—especially after a fresh install or after reactivation. It’s often related to activation status, profile/cache data, or leftover files from an older Office setup

**🔍 Why this happens**

This behavior is usually caused by one of the following:

-   Activation hasn’t fully completed yet or is still syncing
    
-   A corrupted Office identity/profile cache
    
-   Remnants from a previous Office installation
    
-   Updates or compatibility conflicts affecting startup
    

**✅ Step-by-step fix**

1.  **Restart your PC  
    **Restart first. If Office was just installed or recently reactivated, a reboot often finalizes background setup steps.
    
2.  **Check activation status (if you can)**  
    Open an Office app and go to **File > Account**. Look under **Product Information**.
    

If it shows Office is not activated, re-enter your product key or confirm you’re signed in with the correct Microsoft account used for redemption. If you can’t keep an app open long enough, continue with the next steps.

3.  **Run Office Repair**  
    Go to **Control Panel > Programs > Programs and Features**.  
    Select **Microsoft Office** and click **Change**.
    

Run **Quick Repair** first. If the issue continues, run **Online Repair**. This repairs core files without deleting your documents.

4.  **Clear Office credentials and cache**  
    A corrupted cache can cause Office to close immediately.
    

Press **Windows + R**, type the following, and press Enter:

control /name Microsoft.CredentialManager

In Credential Manager, remove entries related to Office (examples: MicrosoftOffice16 or similar Office entries).

Then open **Windows + R** again and paste:

%localappdata%\\Microsoft\\Office\\16.0\\Licensing

(Delete the files inside that folder.)  
If your folder uses a different number, use the one matching your installed Office version.

Restart your PC and try opening Office again.

5.  **Fully remove and reinstall Office (if needed)**  
    If the issue still persists, uninstall Office completely using the uninstall option included in your automatic Office installer (recommended), then reinstall using the installer link from your delivery instructions.
