how to edit NSIS'ed setup file (.exe)?

hi all,

i've got a NSIS'ed setup file, say, aaa.exe

it contains some components (exactly, another setup bbb.exe which is contained in aaa.exe) that i don't need, but provides no option for that

i want to get rid of these components (say, bbb.exe) by my own two hands. it this possible? how to do?

or can i prevent bbb.exe being installed? how?

thx

There's currently no tool that allows you to decompile NSIS installer exe's.
You will just have to modify your source script file and recompile. If you don't have the source file anymore, then tough luck!
