well, I've got a WISE stub package and wise decompiler (e_wise) I got unpacked content from stub expanded to some dll's and something looking like pseudo-sript what's point of interest. What I need is to change the 'script' and inject modified back to the stub (knowing it's a stripped ZIP didn't found the zipped pattern in the stub). Can any1 help me to do this (maybe would be enough to know how2 interpret the 'script' file to be radable -- is there a tool to make easier playing with these 'scripts'?),
helpful link or something, thx in advance.

I dont know how to put script.bin back to orignal setup.exe.However at this site you can found information about wise script file.It is very helpfull document.
