Convert .exe file to source code

Is there a way to dicompile an .exe file to it's source code?

If it's a native exe: no (it's quite difficult and time consuming to work out what it does); if it's a .net exe: partially.

For native exe: IDA Pro Disassembler

In short, no. You can disassemble an executable, but you'll just get assembly language out of it.

No, it's messy, very messy

If it is .NET you can use a nice tool called Reflector http://www.red-gate.com/products/reflector.

If not then you are better off doing whatever you need to do from scratch.

Lies (partially). IDA has a plugin to convert the assembly to C using Hex-Rays Decompiler.

Note it won't ever be able to convert the entire code to C nor will it be able to provide complex functions without you being able to give some input. Function names are not kept either.

What do you do?

Write it (the program) from scratch yourself.

this is reverse engineering and if the program is copyright its illegal

You can disassemble an executable, but if it's of any decent size you'll end up with reams and reams of assembly code, which isn't really much good if you're wanting to make changes to it... so all in all, the answer to your question is no.
