Use these steps:
- Run FSX as an administrator
- In Windows 7, right‑click the Flight Simulator X shortcut.
- Select Properties → Shortcut tab → Advanced.
- Check Run as Administrator, then select OK.
- Start FSX from this shortcut and try activation again.
- If still prompted repeatedly or features are disabled
- While logged on with an administrator account, run the Software Licensing System Reset tool for Flight Simulator X.
- The tool and instructions are described in KB article 928080 (“Error message "1722" when you try to reinstall Flight Simulator X”). Follow that article to download, install, and run the reset tool, then restart the PC and launch FSX again to activate.

If activation still fails after running FSX as administrator, using the reset tool, and ruling out antivirus/firewall interference, use the contact options in the relevant Knowledge Base articles to reach Microsoft support for further activation assistance.
