    Hello Joseph John Crisostomo,

    Unable to start an Office app can be caused by a damaged Office installation, an app hanging in the background, an outdated Windows version, or an add-in or startup conflict.

    I recommend trying these basic checks first:

    • Press Windows + R, enter services.msc, and press Enter. Find Microsoft Office Click-to-Run Service, make sure it is not Disabled, then select Start or Restart if available.
    • Test Word in Safe Mode: press Windows + R, enter winword /safe and press Enter. For Excel, enter excel /safe. If the app opens this way, an add-in or another startup component may be interfering.

    If the issue continues, please confirm:

    1. What exactly happens when opening Office apps? (nothing, a brief loading screen, or an error message)
    2. Which Windows version is installed?
    3. Which exact Office product are you using?
    4. Have you already uninstalled Office and reinstalled it from the Microsoft account connected to the license?

    I look forward to your response so we could determine what to do next!

    Best regards.
