How about a bounty for a new windows installer using inno setup ?

An MSI can't execute an arbitrary executable, just an arbitrary 
DLL which could run an arbitrary executable :) If you're running 
an MSI for security you're screwed.

Now if you're question is why not forgo the MSI and create a 
self-extracting archive which runs a post "install" 
configuration, well then you're writing your own installer and 
will need to fully handle upgrades and uninstall (I say fully 
since even with an MSI there is still uninstall steps you must 
specify, but generally only if you're doing special install steps 
that need to be undone)

To me an MSI is a weird complicated mess, but I'm kind of 
interested to dig in and understand how the MSIexec reads and 
processes the DB (beyond the basics).
