如何在应用程序卸载时删除有条件安装的功能？

Question

我正在使用 wix 构建一个安装程序，该安装程序根据从命令行传入的“CURRENCY”属性安装不同的功能。

msiexec /i install.msi CURRENCY="GBP"

这是wix文件的特征元素：

<Feature Id="Complete" Level="1" Title="My Service" Display="expand" InstallDefault="local">
  <Feature Id="MainProgram" Title="My Service" Display="expand" Level="1" Absent="allow">
    <ComponentRef Id="MyCoordinator" />

    <Feature Id="Foo" Title="Foo" Display="expand" InstallDefault="followParent" Level="1" Absent="disallow">

      <Feature Id="UK" Title="UK Settings" Description="UK Plugin." Level="0" InstallDefault="followParent" Absent="disallow">
        <Condition Level="1">CURRENCY = "GBP"</Condition>   <<-- CONDITION
        <ComponentRef Id="UK_Settings_Component" />
      </Feature>

      <Feature Id="US" Title="US Settings" Description="US Plugin." Level="0" InstallDefault="followParent" Absent="disallow">
        <Condition Level="1">CURRENCY = "USD"</Condition>   <<-- CONDITION
        <ComponentRef Id="US_Settings_Component" />
      </Feature>

    </Feature>

  </Feature>
</Feature>

安装过程很顺利。我传入一种货币并安装相应国家/地区的设置组件。

但是当我尝试通过“添加或删除程序”小程序卸载该应用程序时，它要求用户先卸载该应用程序两次，然后再将其从已安装程序列表中删除。所以我运行从带有详细日志记录的命令行卸载。

> msiexec /x {product-guid} /L*v "uninstall_1.txt"
> msiexec /x {product-guid} /L*v "uninstall_2.txt"

在仔细阅读了详细的卸载日志后，我认为这是因为安装程序无法删除特定于货币的设置组件。

从第二次卸载后的卸载日志我可以看到它发现：

Component: UK_Settings_Component; Installed: Local;   Request: Null;   Action: Local

如果我把货币传给卸载命令，只需要卸载一次

> msiexec /x {product-guid} CURRENCY="GBP"

问题：如何让它在卸载应用程序时始终删除所有货币组件？

Answer 1

Make sure features are always enabled so they can be removed:

The solution is easy, though: Add OR REMOVE to the condition that enables the feature. That ensures the feature is enabled during whole-product uninstall or an attempt to remove that particular feature.
