What you are running into is UAC, Google it if you have not already. You need Execute="deferred" custom actions with Impersonate="no". This will allow your custom actions, and subsequent child processes that they create, to inherit the local system privileges of the Windows Installer service.
There are some situations where deferred actions cannot be used (depending on when the action is sequenced), but give this a try and see what you can come up with.
