Read my solution, i mention the programms used in there. It's ildasm for decompiling the Exe and ilasm for compiling it. You can use the Freflexil-Addin for refelctor, too.

I get an error when I try to run this crackme. It says something like "the application fail to initialize properly. Click Ok to terminate."

Did anyone experience the same issue? I am running a virtual XP machine.
02. Sep 2009
I think you dont have .net framework installed.
