Convert Executable back to Source

[svu]

Dear Friends,

I've got a Executable file whose developer is unknown. There are certain things i need to know from the code of that file. I don't know in what software the file is made from. Anybody would be interested to guide me or take the assignment ? I shall appreciate your response.

You need a decompiler or disassembler. Sometimes, depending on the decompiler or disassembler, you'll need to know what language the program was written in to decode it.

AFAIK, those are your only options.

bjverzal's reply is on target. You also need to
know (I'm sure you do) the operating system. Almost
all programs make OS dependant calls. In a
MS or X Windows environment there are often dynamically
linked libraries that do a lot of the work. Without
knowing these calling conventions you aren't likely
to get very far.

Bottom line, its a big job, even for a relatively
simple program.
