Always update files in minor upgrade (how to)

Question

I am creating an install package using InstallShield Pro X. The upgrade works properly. However, the product manager wants the upgrade to replace all files on an upgrade eve

Answer 1

In investigating this further and testing more options I think the best answer is to modify the product code in addition to the product version and author it as a major upgrade which removes the previous version first and then installs the new files.

The main problem with this is that it takes alot longer for the installer to run. I also think that you can not issue this as a patch, but I could be wrong on that count.
