Cecil,

Was the original work a work for hire or done by employees? If work for hire and your client does not have a written agreement that deeds him the copyrights, it is likely illegal to reverse engineer the application. Being unable to contact the original authors would not be an excuse under the law. Additionally, if you assist in the decompilation, you could be liable too. Penalities are severe (up to $250,000 per incident and jail time). If done by employees, then your client owns the copyrights.

Now, having said that, copyright law is a civil matter and the copyright holders would have to file suit. So, you and your client could be willing to to take the risk. Refox is still available. http://www.refox.net/

>I have a client who needs to reverse engineer his executable file, since there appears to be no soruce code. The programmers up and left (when invited to do so by the company), and took the source code with them. This was in 2004. No one has any idea where the source code is, nor who the programmers were.
