No need to enter a key after an uninstallation!

When installing Application after an uninstallation, there is no need to enter a key. Is it normal?
Do I delete a file or update the registry when uninstalling, so that after the reinstallation the application asks me for the key again?

Hi,

Before installation you need to call DeactivateProduct () function to remove the installation data from the machine.
