I'm trying to load a program coded in C# .NET into IDA, but it always gives me this error when I try opening it as Microsoft .NET assembly:

If I try opening as a Portable Executable it doesn't load it correctly. But I know this can be done because I see people use IDA on .NET programs all the time. And I tried loading it in olly, but olly didn't load it correctly.

What exactly are you trying to do?

Why not just use Lutz Roeder's Reflector?

C# is a .Net language, meaning it doesn't compile to x86 commands that IDA or Olly can understand. Instead it is using the .Net JIT compiler, which generates the executable just before it runs. The .exe that you generate isn't actually an executable program, which is why IDA is having problems.

Samuri gave good advice, just use Reflector to look at the algorithm he's using, and duplicate it in your own program to decrypt the files.

I don't wanna decrypt it. I wanted to hook the Encryption function. And I already know he's using AES anyway.
