WiX Bundle bal:condition - util:RegistrySearch变量总是为false

Question

如果未安装第三方软件元素,我希望我的安装失败.我加了Fragment一个util:RegistrySearch和bal:Condition到Bundle,但我不能得到它的工作.ThirdPartyCOMLibraryInstalled永远不会评估为真.我已经确认密钥存在,并且我使用的值Key是正确的 - 我在regedit中复制/粘贴了所选密钥的名称.日志中没有任何错误.

我正在使用Windows 7 64位的Visual Studio 2012中的WiXTools 3.7构建安装程序,并在Windows XP SP3和Windows 7 64位上进行测试.

在线搜索其他示例,util:RegistrySearch我遇到了条件测试表达式的以下替代形式.

1. ThirdPartyCOMLibraryInstalled = 0 - 总是假的
2. ThirdPartyCOMLibraryInstalled <> 1 - 永远是真的

这是Bundle代码:

Answer 1

根本问题是,它RegistrySearch是一个Fragment永远不会被引用的单独的.因为Fragment引用的内容中没有任何内容,链接器"优化掉"了内容,Fragment并且搜索不包含在您的内容中Bundle.

除此之外:你可以争辩说,在搜索中提到的变量的引用中Condition,链接器应该能够确定搜索是必要的.但是,这并不适用于所有情况.

幸运的是,解决方案非常简单!你甚至必须从以下两种中选择一种:

1. 将RegistrySearch元素移动到Bundle元素.
2. 添加RegistrySearchRef的元素Bundle元素引用RegistrySearch的Fragment.您还需要提供RegistrySearch和Id属性.

就个人而言,我喜欢选项二,我甚Condition至可能会把Fragment所有这些东西组合在一起.类似于:

<Bundle ...>
   <util:RegistrySearchRef Id='SearchForThirdParty' />

   ...

</Bundle>

<Fragment>
   <util:RegistrySearch
          Id='SearchForThirdParty' 
          Variable="ThirdPartyCOMLibraryInstalled" 
          Result="exists"
          Root="HKLM"
          Key="SOFTWARE\Classes\ThirdPartyId.Server\CLSID"/>

    <bal:Condition Message="ThirdParty Application COM Library Required. Please (re)install ThirdParty Application and ensure 'Windows API' and '.Net Components' are installed.">ThirdPartyCOMLibraryInstalled</bal:Condition>
  </Fragment>
</Wix>

应该这样做.
