The activation data deepends on the computer, the version of the operating system, the operating system itself, the version of TurboActivate, and whether you used TA_USER or TA_SYSTEM.
That's a long way of saying it depends, and you shouldn't depend on the activation data being in a certain location because it changes and will change in the future based on technical considerations.
If you want to "remove the activation" then call Deactivate(True);
