卸载和安装会增加报告的应用程序大小 [英] Uninstall and install grows the reported size of the application
问题描述
我用 WiX 编写了一个安装程序；而且效果很好.但是，我遇到了一个小问题，安装程序的报告"大小似乎随着每次后续安装而增长.
I've written an installer in WiX; and it works very well. However, I've having a minor issue where the "reported" size of the installer seems to be growing with each subsequent installation.
步骤
- 安装应用
- 转到控制面板"，选择程序和功能"，找到应用程序并查看大小.
- 卸载应用程序
- 安装应用程序
- 返回控制面板"，选择程序和功能"，找到应用程序并再次查看大小(它大致根据安装程序的大小增大).
有人知道我如何阻止安装之间的增长吗?或者这是设计使然?
Does anyone have any ideas how I stop the growth between installs? Or if this is by design?
推荐答案
您的组件是否将 Permanent 设置为是"?这些组件即使在卸载后也会保留.还要查找 RemoveOnuninstall 属性.
Do your components have Permanent set to "yes"? These components are preserved even after uninstall. Look also for RemoveOnuninstall attributes.
每个程序可能提供也可能不提供自己的大小信息到 Windows.基于 WiX 的程序通常不会，让 Windows 猜测.(在您的项目中搜索 ARPSIZE 以了解您是否这样做.)因此，Windows 不一定会注意到所有文件，但通常报告的所有大小实际上都是通过文件系统获取的并且值得研究.它可能包含由您的程序在 Program Files 下的生成文件.
Each program may or may not provide its own size information to Windows. WiX based programs typically do not and let Windows guess. (Search for ARPSIZE in your project to learn whether you do.) Consequently, Windows does not necessarily notice all of the files, but typically all the size reported is actually taken and worth researching via the file system. It may include files generated by your program somewhere under Program Files.
此大小不包括 Windows Installer 缓存 占用的空间.了解这一点也很有好处，因为它通常与安装的软件本身一样大.MSI 的缓存主要是为了支持更轻松的卸载.
This size does not include space taken by the Windows Installer Cache. This is good to know about, too, as it is often as big as the installed software itself. The MSI is cached primarily to support easier uninstallation.
对于与程序相关的磁盘空间的一次性清理，您可以使用 Windows 清理实用程序.
For a one-time cleanup of program related disk space you can use the Windows Cleanup utility.
