I've used a program called Install Rite. This program basically takes a snapshot of your computer, you place what you need where you need it and also make your registry entries, then Install Rite will take another picture of the differences and create a setup file. It works pretty good. I personally haven't had any problems even with using Active X Controls and registering files. The best part is that its FREE. I think you can find it on ZDNets site under downloads. Give it a try and let me know what you think.
