is there a way to edit already created exe file?

Hello,

I am new to NSIS, but i need to create an installation package. I have an exe file from last version of the tool i need to create a package for. I am pretty sure that exe file was created with NSIS.

I guess what i am asking is this: can one figure out what exe file is actually going to do, so i can create a new installation package without missing anything that used to be installed as part of the installation package?

I tried opening it in text editor... no luck ;0(

Any helps, would be much appreciated.

you can extract the files using e.g. 7zip

you could use process monitor (or the older filemon/regmon) to figure out where the installer is writing/changing files/registry values, though)

you can't really extract the code that the installer goes through when you run it, though. So if there's specific behavior, you'd likely have to deduce that yourself.
