Always perform removal/reinstallation during upgrade
问题 I'm having a little trouble understanding how InstallShield treats upgrades. What I want is to be able to increment the version number on the installer, recompile, and distribute my installer. This should automatically remove any previous version of the application, and install the latest version (and it should be presented to the user as an "upgrade"). This is a very straightforward installer, it just takes output from a few Visual Studio projects (an application EXE, some DLLs and so forth)
