Whoah! before anyone goes installing and using this "patch", be advised that it is not developed, recognized, or endorsed by Adobe. As I understand it, the patch was developed by hackers. For all I know, it works as advertised. But in general, these kinds of hacks can often contain a trojan horse or other malware. The means by which they are distributed (largely P2P networks) subect the hacks to being hacked themselves. So even if the "patch" was pristine when developed, the versions available now might not be. So installing and using these kinds of things is a Very High Security Risk. Be warned!
The safer way to banknote-enable your imaging software is to just use older versions. Earlier versions of Photoshop for example can be found quite cheaply and legally on eBay.
