<p>An installation image for installing an unprotected software product is used to install a protected version of the same product. A protected version of the executable file is embedded in a new installation image with the original installation image, in which the unprotected version of the executable file is damaged so as to be unusable and unreadable. The new installation image causes the original installation image to operate, installing the damaged installation file and other data files. The new installation image then replaces the damaged installation file with the protected installation file.</p> |
