## Troubleshooting Common Activation Issues

If you encounter problems during activation:

This depends on your license type. Retail versions typically allow installation on one PC and one tablet, while volume licenses may permit more installations. Always check your specific license terms.

### What should I do if I lost my product key?

If you purchased digitally, check your email or Microsoft account. For retail purchases without a record, you may need to contact Microsoft Support with proof of purchase.

### How long does a product key remain valid?

Microsoft Office keys don’t expire, but subscription-based versions (Office 365/Microsoft 365) require periodic renewal to maintain access to features and updates.
