    This is a general checklist, and we’ve already done its first checks: PowerPoint is in Applications, and your macOS version is 26.6.2, so it isn’t too old.

    The problem is that macOS refuses to launch PowerPoint. Since the installer also failed its signature check, don’t uninstall or reinstall again yet. Tell Microsoft Support that PowerPoint is installed but won’t launch, and that you haven’t checked Word or Excel.

    I have Microsoft 365 Personal. Microsoft PowerPoint is present in my Applications folder, but it won’t launch. macOS is version 26.6.2. The Office installer said it completed successfully, but PowerPoint still gives the error “kLSNoExecutableErr: The executable is missing.” I also checked the downloaded installer and PowerPoint app, and macOS reported their signatures as invalid. Please help me repair the installation or provide a verified installer. I haven’t checked whether Word or Excel open.

    PowerPoint fails to launch. The installer said installation was successful, but macOS then said the application could not be opened (kLSNoExecutableErr: “The executable is missing”). I also checked the app and installer, and macOS reports that their signatures are invalid. My Mac is running macOS 26.6.2. This is a launch problem, not an activation problem.

    Open PowerPoint directly from Finder → Applications → Microsoft PowerPoint, because a successful installation places Office applications in the Mac’s Applications folder even if no Dock icon was created.^1^

    1. Check whether PowerPoint is actually installed

    1. Open Finder.
    2. Select Applications in the sidebar.
    3. Find Microsoft PowerPoint.
    4. Double-click it.

    Then follow the matching result:

    • PowerPoint opens: Control-click its Dock icon and select Options → Keep in Dock.
    • PowerPoint appears but immediately closes or never displays a window: continue to the compatibility checks below.
    • PowerPoint is missing: reinstall it from the Microsoft 365 Apps page using the Install apps menu. Microsoft recommends Safari when a previous download or installation is incomplete.^1^

    2. Update the new Mac

    1. Select Apple menu → System Settings → General → Software Update.
    2. Install all available macOS updates.
    3. Restart the Mac and try PowerPoint again.

    Microsoft 365 for Mac supports the three most recent major macOS versions. Current Office updates require macOS Sonoma or later, and a new Office 2024 installation also requires Sonoma or later.^2^

    Also check that the Mac has at least 4 GB of memory and 10 GB of available storage, which are the Microsoft 365 Home requirements.^3^

    3. Reinstall only if PowerPoint still closes at launch

    Since the installer already completed successfully, delete the existing Office installation using Microsoft’s Uninstall Office for Mac procedure, restart the Mac, and then download a fresh installer through the Microsoft 365 Apps page. Reinstallation has resolved similar new-Mac PowerPoint failures, although the documented case involved a Mac migration rather than a completely fresh installation.^4^

    Before uninstalling, ensure that the Microsoft account used to purchase or subscribe to Office is available, because it will be needed to activate the new installation.

    4. If it still will not launch

    Check Microsoft’s current PowerPoint for Mac issues page. It does not presently identify a general launch failure matching this description, but it provides the Contact Us support route for Microsoft 365 Home and eligible one-time purchases.^5^

    When contacting support, include:

    • Mac model and macOS version
    • PowerPoint or Office edition
    • Whether the icon bounces and disappears, freezes, or shows an error
    • The exact error message, if any
    • Whether Word or Excel launches normally
