重用InstallShield先决条件
我希望有一个包含多个安装程序但具有单一先决条件源的发布布局，其结构如下：
\Product1\setup.exe
\Product2\setup.exe
\Product3\setup.exe
\Redist
目标是从主位置启动每个先决条件，而不是将每个先决条件复制到其产品文件夹。有没有办法更改InstallShield先决条件（ISSetupPrecessions）的默认位置？
I'm looking to have a release layout with multiple installers but with a single source for prerequisites, in the following structure:
\Product1\setup.exe
\Product2\setup.exe
\Product3\setup.exe
\Redist
The goal is to launch each prerequisite from the master location instead of duplicating each prerequisite to the its product folder. Is there a way to change the default location of InstallShield's prerequisites (ISSetupPrerequisites)?

呵呵，这当然是一个有用的场景，我认为 InstallShield 目前无法处理，但我可以看到两种替代方案。首先，设置下载其有效负载的先决条件，它应该只需要下载一次，因为一旦安装了先决条件，每个后续检查都应该通过。
第二个是，如果您的 CD/DVD 创建程序提供了足够的控制，则应该可以在光盘上的多个位置重复使用相同的文件数据。因此，即使文件被列出多次，它们也不会占用媒体上的额外空间。
Huh, that's certainly a useful scenario I don't think InstallShield handles right now, but I can see two alternatives. First, setting the prerequisites to download their payload it should only need to download once, as once the prerequisite has been installed, each subsequent check should pass.
The second is if your CD/DVD creation program gives enough control, it should be possible to reuse the same file data for multiple locations on the disc. Thus, even though the files are listed multiple times, they don't take up extra room on the media.
