更改安裝目錄WIX引導程序

Question

我在自定義引導程序項目中替換WIX項目的安裝目錄時遇到麻煩。 該解決方案包括3個項目（自定義Bootstrapper，Installer項目和BootstrapperSetup）。

安裝程序項目中的product.wcs如下所示：

<?xml version="1.0" encoding="UTF-8"?>
<?include $(sys.CURRENTDIR)\Settings\settings.wxi ?>
<Wix xmlns="http://schemas.microsoft.com/wix/2006/wi"
     xmlns:bal="http://schemas.microsoft.com/wix/BalExtension">

<Product Id="*" Name="$(var.ProductName)" Language="1033" Version="1.0.0.0" Manufacturer="$(var.Manufacturer)" UpgradeCode="f4c5c824-17e9-4897-9af0-49b2b1225251">
<Package InstallerVersion="300" Compressed="yes" InstallScope="perMachine" />

<MajorUpgrade DowngradeErrorMessage="A newer version of $(var.ProductName) is already installed." />
<MediaTemplate />

<Property Id="PRODUCTNAME" Value="$(var.ProductName)" />
<Property Id="INSTALL_LOCATION" Value="ApplicationInstallDir"/>

<Directory Id="TARGETDIR" Name="SourceDir">
  <Directory Id="$(var.PlatformProgramFilesFolder)" Name="PFiles">
    <Directory Id="DirManufacturer" Name="$(var.Manufacturer)">
      <Directory Id="ApplicationInstallDir" Name="$(var.ProductName)">
        <Component Id="ProductComponent" KeyPath="yes" Guid="28982BC3-BCEA-4EAF-9E7E-9E19A9355CFA">
          <File Id="Norma12" Name="$(var.Norma 12.TargetFileName)" Source="$(var.Norma 12.TargetPath)" DiskId="1" />
          <CreateFolder />
        </Component>
      </Directory>
    </Directory>
  </Directory>
</Directory>

<Feature Id="ProductFeature" Title="InstallerProject" Level="1">
  <ComponentRef Id="ProductComponent" />
</Feature>

</Product>
</Wix>

bundle.wxs看起來像這樣：

<?xml version="1.0" encoding="UTF-8"?>

需要在自定義引導程序中更改變量varInstallLocation ，方法是：

BootstrapperApplication.Engine.StringVariables("varInstallLocation") = s_installDirectory

但是，當我執行保存代碼時，新的安裝路徑不會存儲到變量中，並且該應用程序將安裝在默認位置。 有人可以幫我嗎。

Answer 1

確保在調用Engine.Apply()之前設置了變量。 此后設置的變量將不會提供給鏈接包。
