[英]How to determine install scope of existing app?
I have an installer based on the WixUI_Advanced
that allows users to choose their install scope (per user or machine wide).我有一个基于
WixUI_Advanced
的安装程序,它允许用户选择他们的安装范围(每个用户或机器范围)。
When upgrading (have an existing app with a lower version installed) I would like to hide the install scope screen and automatically select the install scope they chose last time.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选择他们上次选择的安装范围。
How can I tell what install scope was used for the previous installation?我如何知道上次安装使用了哪个安装范围?

Looking at my MSI logs I can see that my existing installation is found: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...
I can see the WIX_UPGRADE_DETECTED
and MIGRATE
properties are set only when the existing installation's scope matches the current installation which makes sense.我可以看到
WIX_UPGRADE_DETECTED
和MIGRATE
属性仅在现有安装的范围与当前安装匹配时才设置,这是有意义的。 Perhaps I can use FindRelatedProducts
directly?也许我可以直接使用
FindRelatedProducts
?
This is not a complete answer.
这不是一个完整的答案。 I had to add as an answer because of formatting requirements.
由于格式要求,我不得不添加作为答案。
UPDATE : Looked at this, ran out of time again.更新:看着这个,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

。
Registry Persistence : I assume you have tried to persist ALLUSERS
and / or the installation scope in the registry and read it back in the updated MSI?注册表持久性:我假设您已尝试将
ALLUSERS
和/或安装范围保留在注册表中并在更新的 MSI 中读回它? I didn't look at that.我没有看那个。 For that to work you have to do it in the first release of the package and keep it up later.
为此,您必须在软件包的第一个版本中执行此操作,并在以后继续使用。
MSI API Automation : Here is a little hack to find the previously installed products on the box (this essentially runs similar stuff as "FindRelatedProducts"
inside MSI files): MSI API 自动化:这里有一个小技巧,可以在盒子上找到以前安装的产品(这基本上运行与 MSI 文件中的
"FindRelatedProducts"
类似的东西):
Inside MSI : MSI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
Standalone, run script directly (install the MSI with the upgrade code specified first):单机,直接运行脚本(先安装指定升级码的MSI):
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"
I was thinking to do something like this in the GUI-sequence, but ran out of time again:我想在 GUI 序列中做这样的事情,但又没时间了:
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 Snippets : 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>
I was going to look at this, but ran out of time.本来想看的,可惜没时间了。 Essentially
WIX_UPGRADE_DETECTED
will be set in the new setup being installed.基本上
WIX_UPGRADE_DETECTED
将在正在安装的新设置中设置。 See this answer for more .有关更多信息,请参阅此答案。 You could use that property to determine whether to hide or show a button.
您可以使用该属性来确定是隐藏还是显示按钮。 I tested that briefly and it worked, but implementing it in WiX is harder.
我对此进行了简短的测试并且它起作用了,但是在 WiX 中实现它更难。 You need to override the whole dialog I think.
我认为您需要覆盖整个对话框。
In MSI tables, it would be something like this (Orca screenshot - MSI viewer tools ):在 MSI 表中,它会是这样的(Orca 屏幕截图 - MSI 查看器工具):
Change Default Dialogs - Advanced Dialogs
). Change Default Dialogs - Advanced Dialogs
)。 Throwing in some more links:抛出更多链接:
I ended up checking for an entry with the DisplayName
matching our app name in the registry in (inspired by this answer ):我最终在注册表中检查了
DisplayName
与我们的应用程序名称匹配的条目(受此答案启发):
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall
Then I grabbed the content of InstallLocation
to determine the install scope: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;
}
