Innosetup already does very reasonable compression, generally better
than winzip, more like the ratios that 7-zip achieve.
You could consider compressing your executables first using, for
example, UPX (http://upx.sourceforge.net/). Using UPX generally leads to
better compression than zip or innosetup, however it _may_ be
incompatible with certain applications and is of no use for datafiles.
About the packing-the-exe-in-zip, i believe this is generally done to
work around firewall/proxy/whatever security issues, i.e. some people
may not be able to download an .exe. Which leaves me wondering why my
system must unpack & copy the same 200MB of data 2 or 3 times...
kind regards,
