Frequently Asked Questions

Can I use an online generator to get a confirmation ID?

No. Third-party confirmation ID generators are unofficial, highly unsafe, and often associated with malware or software piracy. Always use official Microsoft Support channels to protect your device and your license.

Why is Microsoft asking for an installation ID?

An installation ID is generated when you choose to activate your Office product offline or by telephone. It proves that the software is installed on a specific hardware configuration and helps prevent software piracy.

How do I find my Microsoft Office installation ID?

When standard internet activation fails, the Microsoft Office Activation Wizard will typically present an option to 'Activate by telephone'. Selecting this option will automatically generate and display your unique installation ID on the screen.
