If the software activated fine a week ago but now fails, a recent Windows update might have broken it. Use System Restore to go back to a date when activation worked.

Run the installer as administrator, complete the installation, then open Word/Outlook. Enter your activation key manually. This time, it should work.

You used a stolen key. Contact support with proof of purchase to get a replacement. Do not ask for a “free fix”—they will confirm the original key was leaked.

Activation keys usually fail due to minor technical mismatches between your local computer configuration and the licensing server.
