wix - WIX 重新安装功能会增加安装程序的大小

Question

我的设置中有几个功能。我还启用了更改选项。即用户可以在初始安装后更改她/他想要安装或卸载的内容。

当使用此更改选项删除功能时，它会被卸载。我本来希望安装程序的大小会减小，但它保持不变。现在，当稍后使用更改选项添加该功能时，安装程​​序的整体大小会增加。

有没有办法控制它或者它总是这样工作？

注意：安装程序的大小是指它占用的大小或空间（以字节/KB/MB 为单位），显示在“添加/删除程序”中。

The size you are referring to in the Add/Remove Programs is calculated automatically by the MSI engine during the File Costing and is defined by the EstimatedSize registry key.

Usually the correctness of the advertised size is a non-issue for most setup authors and users, so I wouldn't advise putting any effort on this. However if you must fix this, check this SO post:
