Auto-deactivation failed when uninstalling product, what do I do?

Solution:

When uninstalling Gaaiho PDF Suite 3 or 4, the application will release its license automatically. If auto-deactivation fails during un-installation or you have deleted the folder in which Gaaiho is installed in, you may download and run the “Deactivation Tool” to release the license from the computer.

Note: this tool might not work properly after you replace some of the computer’s physical components (e.g. HDD) or change certain system settings.
