The most intuitive setup program I have ever used (and I've used quite a few), and much more advanced than the simple user interface would at first suggest. My only niggle with the product is that it doesn't send your app a WM_CLOSE or similar on an uninstall/reinstall, so your app exe will still be in use and the uninstall will fail to remove the exe file. Many setup programs provide this functionality for you if you specify a Mutex. That said, there are ways around this, e.g. you could add extra code to your app for a command line switch to call from the uninstall that would exit the app etc. Support was good, and it's not overpriced like the big name setup programs. Documentation/Help is ok too, but like I said this program is very easy to use, and the only time I found myself looking at the docs was for the names of internal script constants. Conclusion: If you don't want to spend hours learning how to use a (Windows platform) setup program, but you do want advanced functionality, then I can heartily recommend this product. That said I would wait until version 6 comes out on 19/11/2001.
