    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
