HI, I installed Corel Painter Essentials 3 a few years ago and I want to install it on a Macbook now, but the box with the registration key has been lost. The license is for 3 machines, so that's legal, I have it installed on my iMac running Snow Leopard, so if I can find where the key is stored in my system I think it is one key for up to 3 machines. Anyone know where I can find the key? I have tried reading 3 plist files with Xcode, system.reg, of course under 'About' in Corel, but I have not been able to find it. Intel iMac running Snow Leopard. Thanks.
