    This is my final crackme app as there will be no more. I hope those who download it will enjoy destroying it. I have tried it on XPSP2 & XPSP3 and it will run on both with the proviso it is not blocked by excessive hooking of dlls by firewall, AV or other app. It will also fail to run if it finds anything it does not like in various places. Please read the Readme file before attempting it. Cheers InsaneFIDO FarewellUnWrapMe.zip

    Not an easy crackme, the code is made of the 5-year-old-part, 2-year-old-part and a recently-added-part, i hope you'll like it. The best solution would be the name/key pair, but i can set no restrictions, as it is in real life. (Simply redirecting the wrong key proc to the right key proc is like writing your own code, so it is disallowed:)) And, this one wants a lot of your resources, so you better don't try to solve it while running something else /*I guess, that with everything closed it must be ok everywhere - it worked correct even on the old 633Mhz Celeron. Algorithm can be understood anyway*/ So, as it is said, close all other programs and crack it! Good luck…
