custom policy reverting to Treat as Installer/Updater

I am running an application that I wish to preventing getting keyboard, mouse and screen hooks. I successfully change the application to use a Custom Policy. Here I block Windows/Win Event hooks, Computer Monitor and Keyboard. Howvere the next time I run the application and I think even sometimes when the app has been running for a while it reverts back to Treat as Installer/Updater.

Can someone explain to me please what I need to do to stop this from happening.

Operating system is XP Pro.
