copy /b a.exe+b.exe c.exe </comedy_option_questionmark>

Why do you even WANT do string 2 unrelated pieces of software together this way?

friend of mine asked me if i could ask at some good places for this, he wanted it for someting like postprotection, some years ago he coded something , of course fast and "customer" used it in no disclosure way, but friend had problems with original sources and has no luck to build it again, soo he want code small .exe which will check additional license and if license pass previous oroginal exe will run .. dunno if it is good way ;-)

He could write the code that does the additional check and add it to the end of the original exe's code section, then update the PE header so that the entrypoint is where the new code starts (he'll have to update some of the section descriptors as well).
Just an idea, really. It'd probably be pretty tedious to actually do it.

and immensely easy to bypass with anyone with only a bit of decent programming skill

Sure, but his main concern seemed to be with merging two executables, so that was what I suggested a possible solution for. Cracking has never been an interest of mine, so I don't have any suggestions regarding how to implement copy protection that is hard to crack.
