Reverse engineer C++ DLL

Question

I have a small utility that was originally written in VS2005.

I need to make a small change, but the source code for one of the dlls has been lost somewhere.

Is there a free or reasonably priced tool to reverse engineer the dll back to C++ code.

Answer 1

Hex-Rays decompiler is a great tool, but the code will be quite hard to read and you will have to spend a lot of time to reverse engineer the whole DLL.
