推荐答案

第一个问题是为什么?如果未安装正确版本的Windows Installer，则MSIEXEC甚至在启动之前都会出错.如果将此检查代码放入自定义操作中，那是在浪费时间，因为除非已经安装了最低版本的Windows Installer，否则您的代码将永远没有执行的机会.

The first question is why?? If the correct version of Windows Installer is not installed, MSIEXEC will error out before it even gets started. If you''re putting this check code into a custom action, you''re wasting your time as your code will never get the chance to execute unless the minimum version of Windows Installer is already installed.
