Regarding the issue with Excel displaying as an “Unlicensed Product” and closing automatically after a few minutes of use, this behavior typically suggests that there’s a problem with the activation status of your Microsoft Office installation. Based on [similar cases](https://learn.microsoft.com/en-us/answers/questions/5140864/unlicensed-product-error-unable-to-activate-(offic) reported in the Microsoft Q&A forums, users have experienced this issue even with valid subscriptions. Here are a few steps you can try to resolve it:

1. Check your subscription status: Ensure your Microsoft 365 subscription is active and associated with the correct account.
2. Sign out and sign back in: Sometimes re-authenticating your account can trigger a license refresh.
3. Run Office repair: Go to Control Panel > Programs > Microsoft Office > Change > Quick Repair.
4. Try manual activation: Open Excel, go to File > Account > Product Information, and attempt to activate manually.
5. Update Office: Make sure you’re running the latest version of Office. Please let me know if you need help with any of these steps or have any updates. Best regards, Zoevi
