while defeating the installation it is better to apply some serial keys or licence keys to the user and finding mac address of the system and stops working of application is easy. to stop installation it is difficult to program in shield setup.

Only once means, particular setup file can be installed only once. If some one copies and try to install means that must not be installed.
