推荐答案

如果需要在安装开始时完成，请在PrepareToInstall()或CurStepChanged(ssInstall)事件函数中使用Exec(). 这些都是在用户说继续安装"之后，然后再进行其他操作. PrepareToInstall()还允许您取消安装并发出警告.

If it needs to be done at the beginning of the setup, use Exec() in the PrepareToInstall() or CurStepChanged(ssInstall) event functions. These are both after the user has said "go ahead, install" but before anything else. PrepareToInstall() also allows you to cancel the install with a nice warning.

如果需要首先从设置中提取文件，则可以先使用ExtractTemporaryFile()

If the file needs to be extracted from the setup first, then you can preceed it with ExtractTemporaryFile()
