    Since Repair has already been tried for 3 days and Excel still closes immediately, the next useful check is whether Excel can start in Safe Mode. That separates an add-in problem from an Office installation problem.

    1. Press Windows + R.
    2. Type excel /safe and press Enter.
    3. Confirm Safe Mode by checking the title bar. It should show Microsoft Excel (Safe Mode).

    If Excel opens in Safe Mode:

    1. Go to File > Options > Add-Ins.
    2. In the Manage list, select Excel Add-ins or COM Add-ins, then select Go.
    3. Clear one add-in, select OK, and restart Excel normally.
    4. Repeat one at a time until the crashing add-in is identified.
    5. If present, disable older add-ins first such as Abbyy FineReader, PowerWord, or Dragon Naturally Speaking.

    If Excel does not open in Safe Mode:

    • The issue is not likely caused by add-ins.
    • Run a full Office repair from Windows instead of relying on the repair prompt inside Excel.

    For Windows 11:

    1. Right-click Start and select Installed apps.
    2. Find Microsoft 365 or Office.
    3. Select the three dots > Modify.
    4. Choose Online Repair > Repair.
    5. Let it finish, then restart the PC.

    For Windows 10:

    1. Right-click Start and select Apps and Features.
    2. Select Microsoft 365 or Office.
    3. Select Modify.
    4. Choose Online Repair > Repair.
    5. Restart the PC after it completes.

    If Excel still fails after Online Repair:

    1. Perform a selective startup (clean boot) to check whether another background program or service is conflicting with Excel.
    2. If the issue continues after that, uninstall and reinstall Office.

    The key point is that repeated repair prompts usually require either:

    • disabling a bad add-in if Safe Mode works, or
    • running Online Repair from Windows settings if Safe Mode does not work.

    If you have performed the full online repair from the Settings App - Apps - Installed apps and that did not resolve the problem, then the best option is to completely uninstall Office form there, then go to your account online and reinstall Office from there.

    Before performing this process, please log into your Microsoft account on this link (https://account.microsoft.com/services/) and check to ensure your Office licence or Microsoft 365 subscription is listed correctly on your account.
