Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Hi,
Can you try opening other Office apps, such as Excel or PowerPoint? Are they opening properly?
Please go to: https://account.microsoft.com/services
Can you confirm if your Microsoft 365 subscription appears there and is listed as active?
What changes were made to your Microsoft 365 subscription before this issue started?
In the meantime, try repairing Office to fix any installation issues. In the search bar, type Control Panel > Programs and Features > Microsoft 365/Office > right-click it > Change > select Online Repair.
If the issue persists, press Win + R, type winword /safe, and press Enter to start Microsoft Word in Safe Mode. This temporarily disables add-ins and other non-essential components. If Word opens correctly in Safe Mode, go to File > Options > Add-ins and disable the add-ins one by one to identify if one is causing the issue.
