I worked with Delphi for about a year (liked it a lot) and we used InstallShield. It created a slick, professional looking setup program for our clients and seemed to have all the bases covered. A very mature product. To me it epitomizes the folly of trying to roll your own when there is a relatively inexpensive commercial product available. Even on my most arrogant days I wouldn't expect to be able to develop an equivalent program for the same cost of my labor time.

Charles Hankey and I don't agree on everything but we are on the same page here. He is a big proponent of using tools when they are available. It isn't because he couldn't do it himself; he seems to have become quite a .NET powerhouse. He just doesn't consider reinventing the wheel a good use of his time.
