Question

我想用我的应用程序安装Visual C ++ 2012重新分发。我想根据机器的架构安装适当的版本。例如

if platfrom is x86
    vcredist_filename = Microsoft_VC120_CRT_x86.ms
else
    vcredist_filename = Microsoft_VC120_CRT_x64.ms

我试图以许多不同的方式完成，但我不能让它工作。我尝试了什么：

    <?if $(var.Platform) = x64 ?>
        <?define VC120Redist_FileName="Microsoft_VC120_CRT_x64.msm" ?>
    <?else ?>
        <?define VC120Redist_FileName="Microsoft_VC120_CRT_x86.msm" ?>
    <?endif ?>

    (undefined preprocesss variable "Platform").

    <?if $(var.VersionNT64) ?>
        <?define VC120Redist_FileName="Microsoft_VC120_CRT_x64.msm" ?>
    <?else ?>
        <?define VC120Redist_FileName="Microsoft_VC120_CRT_x8.msm" ?>
    <?endif ?>

     (undefined preprocesss variable "VersionNT64").

    <?if ![CDATA[VersionNT64]] ?>
        <?define VC120Redist_FileName="Microsoft_VC120_CRT_x64.msm" ?>
    <?endif?>

     (unexpected literal ![CDATA[VersionNT64]])

我可能会使用两个单独的组件，条件如下：

<Component Id="Foo" Guid="{GUID}" Win64="yes"> 
  <Condition>
    <![CDATA[VersionNT64 OR $(var.Platform) = "x64"]]>
  </Condition>
</Component>

<Component Id="Bar" Guid="{GUID}">
  <Condition>
    <![CDATA[NOT(VersionNT64) OR $(var.Platform) = "x86"]]>
  </Condition>
</Component>

检测32位或64位窗口并定义var
