greets BR You need to run the patch file directly, the Installshield system is a protection that installs the package into a secure RAM disk, which contains a dialogue system, the game's script locking utility, and a few "search and replace" tools to change the game's character systems for fair gameplay. The whole shebang is all done in RAM, to prevent armchair hackers from discovering ways to put back the hi-kill settings the patch takes down. You won't be able to unpack it with UniExtract as the patch's version of Installshield prevents access to the encrypted data inside.
