You have to bypass the registration and get rid of the NAG on the program to make the program think it's valid.

Language : .NET Platform : Windows x64 OS Version : All Packer / Protector : Modified ConfuserEx Description : This is a heavily modified version of ConfuserEx, mostly custom, some copied from other obfuscators seen in the wild. I believe this to be difficult to reverse to some extent, but definitely not even close to impossible. (Also ignore old Discord ID added I changed accounts a while ago.) Also, please document how you were able to reverse it, and post the serial key. Thank you! Screenshot : Download: CrackMeO.exe

Language: .NET Platform: Windows x32/x64 OS Version: Tested on Windows 10, with .NET 4.6.2 Packer / Protector: WinterStorm 0.1 (Personal Project) Description: Here is a project I've been working on for the last 6 months. It's a follow-up to my previous DynamicMethod attempts. This time I also included some simple JIT hooking. Everything here was written by myself, except a helper class for loading dlls from memory. I hope you'll find it entertaining. I can't wait to hear your thoughts. This is (arguably) the best iteration of the popular game, MineSweeper. Unfortunately, it's a demo, and it only allows for 5 moves. In order to keep playing you have …

Language : .NET Platform : .NET/Mono OS Version : All Packer / Protector : Custom Description : This is something I've stopped working on over the last few months, but if someone's interested in taking up the project with me I'll gladly accept. The original password is hashed to prevent string equality hooking, so the goal here is just to make it respond correctly. Cracking : If you do crack this, please post in the thread (or DM me) about how you did it. It doesn't have to be step-by-step; a simple "after doing X all you need to do is Y" is fine. If you have any suggestions for additional obfuscation, please include those as well.…
