    Hi Richard, I see you pressed No below my post. May I know if the steps provided by Stefan and myself did not help?

    Which type of repair did you try? If you haven't tried an Online Repair, that would be the next logical step. See https://support.microsoft.com/en-us/office/repair-an-office-application-7821d4b6-7c1d-4205-aa0e-a6b40c5bb88b .

    More troubleshooting steps can be found in the article at https://learn.microsoft.com/en-us/troubleshoot/microsoft-365-apps/word/issues-when-start-or-use-word (ignore the fact that Word 2024 or Word 365 are not mentioned in the list of versions).

    Hi Richard,

    It seems like an update caused this problem. Let us start from scratch.

    Microsoft offers a free tool called the Microsoft Support and Recovery Assistant (SaRA). This tool is designed to fix Office installation problems and can also help you fully uninstall Office when other methods fail.

    Here is how to use it:

    https://yourwindowsguide.com/2026/02/how-to-uninstall-microsoft-office.html#google_vignette

    Next step, You can reinstall Microsoft Office from the https://account.microsoft.com/services page by selecting the relevant option.

    Let me know if that solves the issue.

    I’m eager to hear back and work together to find a solution.

    Follow these steps in order, testing Word after each major step.

    1. Start Word in Office Safe Mode via Run
      1. Close all Office apps.
      2. Press Windows key + R to open Run.
      3. Type: 
              winword /safe
        then select OK.
      4. Confirm that the title bar shows “Microsoft Word (Safe Mode)” if it opens.
    2. If Word opens in Safe Mode, disable add-ins
      1. In Word (Safe Mode), go to File > Options > Add-Ins.
      2. At the bottom, in Manage, choose COM Add-ins (or the Word-specific Add-ins entry) and select Go.
      3. Clear all check boxes to disable all add-ins, then select OK.
      4. Close Word, then start Word normally (without /safe).
      5. If Word now opens, re-enable add-ins one at a time, restarting Word after each, until the failing add-in is found. Leave that add-in disabled or remove it. Older add-ins such as ABBYY FineReader or Dragon Naturally Speaking are known to cause issues and should be unchecked first if present.
    3. If Word does not open even in Safe Mode If winword /safe fails to start Word, the issue is not caused by add-ins. a. Run an Online Repair of Office
      1. Close all Office apps.
      2. Open Settings > Apps (or Apps & features).
      3. Find the Microsoft 365/Office installation in the list.
      4. Select it and choose Modify.
      5. Choose Online Repair (full repair) and run it. This may effectively reinstall Office and can take some time.
      6. After completion, restart Windows and test Word again.
    4. If Online Repair and reinstall still do not fix it A deeper configuration or registry issue may be present. For Word-specific problems that persist after repair and reinstall, registry-based troubleshooting is often required. Typical steps include backing up and then deleting Word’s user-specific registry keys (such as the Word Data and Word Options keys) so Word recreates them cleanly on next start. This type of registry work should be done carefully, ideally with support assistance, because incorrect edits can affect the system or Office installation.

    If none of the above resolves the issue, contact Microsoft Support and mention that Word will not start even in Office Safe Mode and that Online Repair and reinstall have already been tried; this will help support focus on registry/profile-level causes.
