Installshield Setup/Patch/Upgrade question.

Question

Hi! I hope someone can answer my questions. I made an installer using Installshield. Then also about 5 patches because of some bugs and everything. Now here are my questions:

1. Is it possible to make new installer based on the previous one, like an upgrade, but with the patched file on it and not the original files?
2. Supposed that question 1 is possible, and then I made another patch based on the new installer. But then, a user who is using the previous installer installed in his computer downloaded the patch based on the new installer and installed it. Is it a valid patch also because the new installer is based on the previous one?

Please note that I am not an installshield master and I would be thankful if someone could answer my questions or give some helpful links.

Answer 1

This is really advanced stuff, but there's no better source than the Windows Installer documentation: Patching and Upgrades
