如何确定现有应用程序的安装范围?

How to determine install scope of existing app?

我有一个基于 WixUI_Advanced 的安装程序,允许用户选择他们的安装范围(每个用户或机器范围)。

升级时(安装了较低版本的现有应用程序)我想隐藏安装范围屏幕并自动 select 他们上次选择的安装范围。

如何判断上次安装使用的安装范围?

查看我的 MSI 日志,我可以看到找到了我现有的安装:

// Existing user specific installation
FindRelatedProducts: Found application: {C5D3DCD0-4A97-4224-AF22-BDDEB357EEB7}
MSI (c) (C4:F0) [11:11:39:289]: PROPERTY CHANGE: Adding WIX_UPGRADE_DETECTED property. Its value is '{C5D3DCD0-4A97-4224-AF22-BDDEB357EEB7}'.
MSI (c) (C4:F0) [11:11:39:289]: PROPERTY CHANGE: Adding MIGRATE property. Its value is '{C5D3DCD0-4A97-4224-AF22-BDDEB357EEB7}'.

// Existing machine wide installation
MSI (c) (2C:4C) [11:03:19:258]: FindRelatedProducts: current install is per-user.  Related install for product '{C5D3DCD0-4A97-4224-AF22-BDDEB357EEB7}' is per-machine.  Skipping...

我可以看到 WIX_UPGRADE_DETECTEDMIGRATE 属性只有在现有安装的范围与当前安装的范围匹配时才设置,这是有道理的。也许我可以直接使用 FindRelatedProducts

This is not a complete answer. I had to add as an answer because of formatting requirements.


UPDATE: 看了这个,运行又没时间了。 This really is no answer at all, but just lobbing it to you in case it can help you research it yourself.

注册表持久化:我假设你已经尝试过持久化ALLUSERS和/或注册表中的安装范围并在更新的 MSI 中读回?我没看那个。为此,您必须在软件包的第一个版本中执行此操作,并在以后保持它。

MSI API Automation:这里有一个小技巧,可以在盒子上找到以前安装的产品(这基本上运行s 类似于 MSI 文件中 "FindRelatedProducts" 的内容):

微星内部:

Set upgrades = Session.installer.RelatedProducts("INSERT-UPGRADE-CODE")
For Each u In upgrades
    scope = Session.installer.ProductInfo(u,"AssignmentType")
    MsgBox CStr(scope)
Next

独立,运行直接脚本(安装MSI先指定升级码):

Set installer = CreateObject("WindowsInstaller.Installer")
Set upgrades = installer.RelatedProducts("INSERT-UPGRADE-CODE")

For Each u In upgrades
   MsgBox "Product Code: " & u & vbNewLine & "Installation Context: " & installer.ProductInfo(u,"AssignmentType")   
Next

MsgBox "Done"

我本来想在GUI-sequence做这样的事情,但是运行又没时间了:

If scope = 1 Then
  Session.Property("ALLUSERS") = "1"
  Session.Property("MSIINSTALLPERUSER") = ""
  Session.Property("WixAppFolder") = "WixPerMachineFolder"
Else
  Session.Property("ALLUSERS") = "2"
  Session.Property("MSIINSTALLPERUSER") = "1"
  Session.Property("WixAppFolder") = "WixPerUserFolder"
End If

WiX 片段:

<Binary Id='Scope.vbs' SourceFile='Debugging Custom Actions\Scope.vbs' />
<CustomAction Id='Scope.vbs' VBScriptCall='' BinaryKey='Scope.vbs' Execute='immediate' Return='ignore'/>

<..>

<InstallUISequence>
  <Custom Action='Scope.vbs' Before='CostInitialize' />      
</InstallUISequence>

本来想看这个的,但是运行没时间了。本质上 WIX_UPGRADE_DETECTED 将在正在安装的新设置中设置。 See this answer for more。您可以使用 属性 来确定是隐藏还是显示按钮。我对其进行了简要测试并且它有效,但在 WiX 中实现它更难。我认为您需要覆盖整个对话框。

在 MSI 表中,它会像这样(Orca 屏幕截图 - ):

我最终检查了 DisplayName 与我们在注册表中的应用程序名称相匹配的条目(受 this answer 启发):

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall

然后我抓取了InstallLocation的内容来确定安装范围:

if (installLocation == string.Empty)
{
    // Installed before we introduced scope => never set install location
    return ExistingInstallation.MachineWide;
}
else if (installLocation.Contains(_programFilesPath))
{
    return ExistingInstallation.MachineWide;
}
else
{
    return ExistingInstallation.UserSpecific;
}
