Just download that, and it comes with an installation file if you don't already have the program. Once downloaded, you will need Winrar (just google that if you dont have it and download it), and unzip the file using winrar. Once that has been done, replace the file in the Hypercam directory (e.g. C:/Program Files/Hycam2) called "Hycam2" with the crack called "Hycam2". Once that has been done, run the program and it should be cracked.
I made this video in Runescape with the cracked Hypercam2. If you have any questions, please post them here! Enjoy and please comment! Add me on Runescape: Spongebrett8.
