Unless you already have it, get hold of IS Tool for Inno Setup and
enable 7-zip compression there (or just apply 7-zip to the finished
executable file). You'll be pleased by the results in
terms of download size. An auto-extracting 7-zip file is usually much
smaller than the corresponding zip file.

As an example, I have made a setup script for a rather large
application:

uncompressed: 15MB.
zip (maximum): 6.5 MB
7-zip: 2.5 MB

Your mileage may vary.
Ciao
