installer included in install dir

Hi

I need my just build installer in my InstDir, so i can access it simply.

My first aproach was
File installer.exe

which work fine, with the drawback that the resulting file was very very Large!!

I thing that there "should/must" be a build-in command to do this work - isnt it so?

If not - has somebody a better idea to do this work?

Greetings,
Daniel
