Freeware installer recommendation?

I have been using Null Soft's product and frankly, I just don't get the NSI scripting language. It just seems too arcane and doesn't seem to flow right -- if you know what I mean. I spend more time digging through the help docs and Googling to figure out how to get something going.

I would welcome any alternative tool recommendation -- freeware of, course :) My target environment is Windows and so the tool doesn't have to be cross-platform capable.
