</Wix> --------------------编程问答-------------------- 补充一下：我主要是想用msi文件调用外部的exe文件，我的脚本如上，我在安装的时候没有问题，卸载的时候，控制面板的“Test Package”卸载不了，是不是我的脚本哪里出问题了？ --------------------编程问答-------------------- 应该是uscuninstall.exe文件安装时没见拷贝，卸载时找不到，CustomAction失败导致无法卸载的吧。

<CustomAction Id="ManagedUninstall"
           Directory='TestDir'
           ExeCommand='"[WindowsFolder]\system32\uscuninstall.exe"'
   Return='check'>
       </CustomAction>
--------------------编程问答-------------------- 我都是在界面直接输入相关参数做的,进步中 --------------------编程问答-------------------- 卸载的时候

<CustomAction Id="ManagedUninstall"
           Directory='TestDir'
           ExeCommand='"[WindowsFolder]\system32\uscuninstall.exe"'
   Return='check'>
        </CustomAction>
可以执行的到，就是test package在控制面板里卸载不掉，导致第二次安装失败 --------------------编程问答-------------------- 可以参考
