在 WiX 中更改 TARGETDIR [英] Changing the TARGETDIR in WiX

问题描述

我在设置 TARGETDIR 路径时遇到问题.我使用 dark.exe 对一个有效的 MSI 文件进行逆向工程并阅读我能找到的关于这个主题的任何帖子，但我似乎无法将 TARGETDIR 设置为指向路径 ProgramFiles\制造商\产品.以下是我的 WXS 文件的提炼，它导致我的应用程序出于某种原因安装到我的 D 驱动器的根目录:

I am having problems setting the TARGETDIR path. I used dark.exe to reverse engineer a working MSI file and read any posts I could find on this subject, but I seem to be unable to set the TARGETDIR to point to the path ProgramFiles\Manufacturer\Product. Below is a distilation of my WXS file which results in my application being installed to the root of my D-drive for some reason:

<?xml version="1.0" encoding="UTF-8"?>
<Wix xmlns="http://schemas.microsoft.com/wix/2006/wi">
    <Product Id="*"
             Name="FBL - Some App"
             Language="1033"
             Version="1.0.0.0"
             Manufacturer="Foo &amp; Bar Limited"
             UpgradeCode="780286c6-e064-4402-80d8-dd2c68b56c04">
        <Package InstallerVersion="200"
                 Compressed="yes"
                 InstallScope="perMachine"
                 Comments="Performs some operation that is important" />

        <Media Id="1" Cabinet="App.1.0.0.cab" EmbedCab="yes" />
        <CustomAction Id="setTARGETDIR"
                      Property="TARGETDIR"
                      Value="[ProgramFilesFolder][Manufacturer]\[ProductName]"
                      Execute="firstSequence"
                      Return="check" />

        <Directory Id="TARGETDIR" Name="SourceDir">
            <Component Id="C__App.exe"
                       Guid="{074586E9-A675-2734-A4CD-1CE520922A41}">
                <File Id="F__App.exe"
                      Name="App.exe"
                      KeyPath="yes"
                      Assembly=".net"
                     AssemblyManifest="F__App.exe"
                      AssemblyApplication="F__App.exe"
                      DiskId="1"
                      Source="D:\SomePath\bin\Debug\App.exe" />
            </Component>
        </Directory>
        <Feature Id="DefaultFeature" ConfigurableDirectory="TARGETDIR" Level="1">
            <ComponentRef Id="C__App.exe" Primary="yes" />
        </Feature>
        <Icon Id="favicon.ico" SourceFile="d:\SomePath\favicon.ico" />
        <Property Id="ARPPRODUCTICON" Value="favicon.ico" />
        <UI />
        <InstallExecuteSequence>
            <Custom Action="setTARGETDIR" Before="CostFinalize" />
        </InstallExecuteSequence>
    </Product>
</Wix>

我确定我遗漏了一些简单的东西，但我无法从这里找到有关该做什么的更多信息.

I'm sure I am missing something simple, but I cannot find any further information on what to do from here.

推荐答案

需要进行以下修改:

<CustomAction Id="SetTARGETDIR"
              Directory="TARGETDIR"
              Value="[ProgramFilesFolder][Manufacturer]\[ProductName]"
              Return="check" />

和

<InstallExecuteSequence>
    <Custom Action="SetTARGETDIR" After="InstallValidate" />
</InstallExecuteSequence>

说明:使用 Directory 属性而不是属性(它是类型 35 的自定义操作)并在执行序列中的 InstallValidate 之后安排此操作 - 那是检查目录的写访问权限并真正设置的时间.

Explanation: Use the Directory attribute instead of a property (it's a type 35 custom action) and schedule this action after InstallValidate in the execute sequence - that's when directories are checked for write access and truly set.
