devsoft on 2023-05-29 10:06: I'm going to write a solution for this Crackme with and without debugger, if it gets approved, it may answer your doubts with some luck.

mlmn21 on 2023-06-04 12:53: thanks @devsoft i finally got it.

bang1338 on 2024-08-22 08:41: Solved! I do remember that a RedXen's crackme (64d928e6b25df8732eebc872) do have same protection like this, but advanced like anti decompiler (but didn't stop from IL). Ye I do read a bit a solution from devsoft, but AntiDbg somehow didn't work, found le key :v Solution soon, I'm too tired.

SharpBritannia on 2025-06-04 14:02: Compiling for x86 adds nothing of value in most .NET challenges; It's just annoying that I have to use 32 bit tools. Please let x86 die
