Boy, isn't this the truth?

I have started using Inno installer on Windows. You can use it's built 
in scripting language to do whatever you want. It compiles the 
installation into a setup.exe for you. This contains all the files and 
the script to do whatever you want. I have even seen it detect missing 
.net versions and offer to go fetch and install them. As far as 
uninstall goes, you can tell it exactly what to do. It's similar to 
Installshield in many ways except the one I find most important... 
source code is available (not open source) and the price is right...  free.

This is a very nice installer for Windows.

And, there is a support community built up around it. This allows you to 
have an expert build you your first scripts and then you can expand them 
from there. Makes it a lot quicker to get a basic install working.
