Question

我对WIX安装程序有一个奇怪的问题。它具有自定义操作，阻止应用程序在较新版本存在时安装：

<Upgrade Id='SOME_GUID'>
  <UpgradeVersion OnlyDetect='yes' Property='SELFFOUND'
    Minimum='$(var.Version)' IncludeMinimum='yes'
    Maximum='$(var.Version)' IncludeMaximum='yes' />
  <UpgradeVersion OnlyDetect='yes' Property='NEWERFOUND'
    Minimum='$(var.Version)' IncludeMinimum='no' />
</Upgrade>

<InstallExecuteSequence>
  <Custom Action='AlreadyUpdated' After='FindRelatedProducts'>SELFFOUND</Custom>
  <Custom Action='NoDowngrade' After='FindRelatedProducts'>NEWERFOUND</Custom>
<InstallExecuteSequence>

<CustomAction Id='AlreadyUpdated' Error='$(var.ProductName) has already been updated to $(var.Version) or newer.' />
<CustomAction Id='NoDowngrade' Error='A later version of $(var.ProductName) is already installed.' />

没什么特别的 - 就像在WIX教程中一样。我使用Mondo UI，几乎没有自定义对话框。

<UIRef Id="WixUI_Mondo" />

问题在完成所有配置步骤后，单击“安装”按钮后执行自定义操作“NoDowngrade”。我希望在启动安装程序后立即看到该消息。我使用Orca util检查了安装程序表中的installExecuteSEquence - “AlreadyUpdated”CA具有Sequence = 27. FindRelatedProducts事件具有Sequence = 25。我的其他动作“NoDowngrade”使用了27，与“AlreadyUpdated”几乎相同。应该在Sequence = 49上显示第一个UI对话框。我想 - PrepareDlg在InstallUISequence中具有此值。看起来除了我的自定义操作之外，FindRelatedProducts和PrepareDlg之间什么都不会发生。

但令人惊讶的是，安装日志反过来说：

因此我们可以看到FindRelatedProducts尝试执行两次，但AlreadyUpdated CA仅在第二次尝试时执行。教程没有说明如何在InstallUISEquence中放置此CA.它是否需要，或者如果不存在它可能不是一个好方法？或者你能为这个问题推荐更好的解决方案吗？

Answer 1

也为InstallUISequence重复InstallExecuteSequence部分。您希望在对话期间进行检查，因此它们是InstallUISequence的一部分。您还希望它们在InstallExecuteSequence期间发生，以防用户进行安静的安装，跳过UI。

<InstallUISequence>
  <Custom Action='AlreadyUpdated' After='FindRelatedProducts'>SELFFOUND</Custom>
  <Custom Action='NoDowngrade'    After='FindRelatedProducts'>NEWERFOUND</Custom>
<InstallExecuteSequence>

<InstallExecuteSequence>
  <Custom Action='AlreadyUpdated' After='FindRelatedProducts'>SELFFOUND</Custom>
  <Custom Action='NoDowngrade'    After='FindRelatedProducts'>NEWERFOUND</Custom>
<InstallExecuteSequence>
