在我当前的 MSI ExecuteAction 至少需要 1m 30s.我创建了一个简单的 msi(来自 WiX 示例)，ExecuteAction 大约需要 4 秒.

In my current MSI ExecuteAction takes at least 1m 30s. I created a simple msi (from WiX examples) and it takes about 4 seconds for ExecuteAction.

如何优化我的 MSI 包，让 ExecuteAction 运行得更快?

How can I optimize my MSI package, so ExecuteAction will run faster?

推荐答案

Windows 使用 ExecuteAction 来启动 系统还原点.根据您的机器配置，这可能需要很长时间.在对我们公司的安装程序进行性能测试时，我们遇到了 5 到 26 秒的运行时间.

Windows uses ExecuteAction to initiate a system restore point. Depending on your machine configuration, this can take quite a while. During performance testing our company's installer, we encountered elapsed times of 5 to 26 seconds.

Windows XP 似乎在默认情况下不会创建系统还原点.但是，Windows Vista 和 Windows 7 可以.以下是我们在 24 台机器上的测试结果(平均值):

Windows XP, it seems, by default, does not create system restore points. Windows Vista and Windows 7, however, do. Here are our test results over 24 machines (averages):

• Windows XP:1 秒
• Windows Vista:7 秒
• Windows 7:13 秒

有一个适用于 Windows 7 的解决方法(在 Windows Installer 5 中).这是 MSDN 文章.解决方法是禁用安装程序的系统还原点.以下是 WiX 中的解决方法:

There is a workaround for Windows 7 (in Windows Installer 5). Here is the MSDN article. The workaround is to disable the system restore point for the installer. Here is the workaround in WiX:

<Property Id="MSIFASTINSTALL" Value="1"/>

这里是与您的问题相同的另一个示例，我在其中找到了解决方案.

Here is another example of the same problem as yours where I found the solution.
