WiX:从RegistrySearch设置安装目录会导致错误"；无法访问网络位置“；

我正在制作一个基于WixUI_Advanced的安装程序。我使用的解决方案如下：

但是，我希望安装程序记住以前的安装目录。试图设置APPLICATIONFOLDER属性会导致错误“无法访问网络位置”，后跟目录名。只有在注册表中实际找到值时（升级程序时），才会发生这种情况

以下是相关代码：

<Product Id="*" Name="$(var.ProductName)" Language="1033" Version="$(var.Version)" Manufacturer="OronDF343" UpgradeCode="22187c5e-5fd6-4734-802e-236abd321433">
    <Package InstallerVersion="200" Compressed="yes" InstallScope="perMachine" Description="$(var.ProductName)" />

<PropertyRef Id="NETFRAMEWORK45" />
<Condition Message="This application requires .NET Framework 4.5.1 or later. Please install .NET Framework version 4.5.1 or higher and then run this installer again.">
  <![CDATA[Installed OR (NETFRAMEWORK45 >= "#378758")]]>
</Condition>

    <MajorUpgrade AllowSameVersionUpgrades="yes" DowngradeErrorMessage="A newer version of $(var.GlobalProductName) is already installed." />

<!-- This is where the problem is. This is how it was implemented in the solution linked above, but I have tried it without the SetDirectory. -->
<Property Id="APPLICATIONFOLDER" Secure="yes">
  <RegistrySearch Id="RegistrySearch" Type="raw" Root="HKLM" Win64="$(var.Win64)" Key="Software\$(var.Company)\$(var.ProgID)" Name="InstallLocation" />

<SetDirectory Id="APPLICATIONFOLDER" Value="[$(var.PlatformProgramFilesFolder)]$(var.GlobalProductName)">APPLICATIONFOLDER=""</SetDirectory>

    <MediaTemplate EmbedCab="yes" />

<Directory Id="TARGETDIR" Name="SourceDir">

    </Directory>
  </Directory>
  <Directory Id="ProgramMenuFolder">

  <Publish Dialog="ExitDialog" Control="Finish" Event="DoAction" Value="LaunchApplication">WIXUI_EXITDIALOGOPTIONALCHECKBOX = 1 and NOT Installed</Publish>

<!--Hacks for WixUI_Advanced install folder-->
<CustomAction Id="OverwriteWixSetDefaultPerMachineFolder" Property="WixPerMachineFolder" Value="[APPLICATIONFOLDER]" Execute="immediate" />
<CustomAction Id="SetARPINSTALLLOCATION" Property="ARPINSTALLLOCATION" Value="[APPLICATIONFOLDER]" />

  <Custom Action="SetARPINSTALLLOCATION" After="InstallValidate"/>
</InstallExecuteSequence>
</Product>

= "#378758")]]>
APPLICATIONFOLDER=“”
WIXUI_EXITDIALOGOPTIONALCHECKBOX=1且未安装

编辑：我没有包含保存注册表值的代码，但它被保存为“'[APPLICATIONFOLDER]”，并删除了双引号，为新安装修复了它。

同样忘记了SetDirectory中的括号

我会创建一个详细日志，看看实际的属性值是什么。当结果看起来不像驱动器号路径时，您会收到该消息，因此它尝试将其作为网络路径，但失败。在错误消息中，它会说“无法访问网络位置”，然后是正确的路径。这不意味着属性设置为该值吗？我很好奇实际路径，以及您的设置是否为32位并试图对本机64位文件夹执行某些操作。我不知道该链接的哪一部分包含您正在使用的解决方案，但您将很难打破有关尝试从32位安装程序安装到64位位置的规则。只有64位MSI可以将64位组件安装到64位位置，如本机程序文件目录。我正在64位操作系统上安装一个64位软件包。看起来需要详细日志，请使用包含/l*vx的命令行安装，如果没有明确的原因，让我们来看看。
