- not provided
- Scenario

Identify Symptoms and Gather Necessary Diagnostic Information
Pinpoint the exact nature of the problem and collect error details to determine the correct troubleshooting path.
The phrase 'Office is not working' covers a broad range of issues. To fix the problem, you must first isolate whether the failure is happening during installation, activation, software startup, or while performing a specific task inside an app like Word or Excel.
Determine whether you are using a subscription-based product like Microsoft 365 (Personal, Family, or Business) or a one-time purchase such as Office 2021 Home & Student.
Identify the specific failure point. Note whether Office fails to install entirely, prompts for activation repeatedly, crashes immediately upon opening, or only freezes when saving a document.
Write down the exact wording of any error dialog boxes or numerical error codes (e.g., Error 0x80040154). Take a screenshot of the error, making sure to blur or crop out personal information like your email address.
Run the Built-in Office Repair Tool
Use the Windows Control Panel to automatically repair corrupted or missing Office installation files.
Switch to WPS Office When Microsoft Office Fails

Frequently Asked Questions
Why is my Microsoft Office app crashing immediately after startup?
Startup crashes are frequently caused by incompatible or corrupted add-ins. To test this, hold down the 'Ctrl' key while clicking the application shortcut to open it in Safe Mode. If it opens successfully, navigate to File > Options > Add-ins to disable them and find the culprit.
How do I fix a 'Microsoft Office activation failed' error?
Ensure your computer is connected to the internet and that you are signed in with the Microsoft account associated with your subscription. You can also run the Microsoft Support and Recovery Assistant to automatically diagnose and fix subscription validation issues.
What should I do if my Office installation or update is stuck?
A stuck installation is usually caused by network interruptions or conflicting background processes. Restart your computer, temporarily disable third-party antivirus software, and try launching the update again from within any Office app by going to File > Account > Update Options.
Can I view my Office documents without an active Microsoft subscription?
Yes. If your Microsoft Office is broken or expired, you can install a free alternative like WPS Office. It seamlessly opens standard Microsoft Office formats natively, allowing you to view and edit your files without any active Microsoft subscription.
