Online authentication … what about de-authentication?
You can de-authenticate the game. De-authentication means to return one authentication to the “pool” of available activations (which started with 10 available).
You do it one of two ways:
1. In the Games Explorer in Vista: right-click on the game’s Icon and select “Deauthorize this machine”
2. Uninstall the game; uninstallation will automatically invoke the de-authentication process.
After de-authentication, you are told how many authentications are now in the “pool”.
SecuROM needs to go online to de-authenticate.
