Visual Studio 先决条件安装已安装的包

Question

我正在使用 VS 2015，其中 visual studio 2012 的 Visual C++ Redistributable 没有先决条件。所以我创建了一个自定义引导程序并存储在 VS 引导文件夹中。

package.xml

<Package
  xmlns="http://schemas.microsoft.com/developer/2004/01/bootstrapper"
  Name="DisplayName"
  Culture="Culture"
>
    <Strings>
        <String Name="DisplayName">Visual C++ 2012 Runtime Libraries (x86)</String>
        <String Name="Culture">en</String>
        <String Name="AdminRequired">You do not have the permissions required to install Visual C++ 2012 Runtime Libraries (x86). Please contact your administrator.</String>
        <String Name="InvalidPlatformWin9x">Installation of Visual C++ 2012 Runtime Libraries (x86) is not supported on Windows 95. Contact your application vendor.</String>
        <String Name="InvalidPlatformWinNT">Installation of Visual C++ 2012 Runtime Libraries (x86) is not supported on Windows NT 4.0. Contact your application vendor.</String>
        <String Name="GeneralFailure">A failure occurred attempting to install Visual C++ 2012 Runtime Libraries (x86).</String>
        <String Name="VCRedistExe">https://download.microsoft.com/download/1/6/B/16B06F60-3B20-4FF2-B699-5E9B7962F9AE/VSU_4/vcredist_x86.exe</String>

    </Strings>
</Package>

这是product.xml

安装程序下载并安装 visual studio 2012 的 Visual c++ 可再发行组件。但问题是即使在安装之后，我再次运行安装程序再次下载并尝试安装C++ 重新分发。我觉得问题出在 product.xml 。有什么办法可以解决这个问题？？

Answer 1

经过小小的研究，我发现 "Visual C++ 2012 Runtime Libraries (x86)" 的版本是 11.0，而不是你提到的 12.0。在您的 product.xml 中试试这个：

<Product
  xmlns="http://schemas.microsoft.com/developer/2004/01/bootstrapper"
  ProductCode="Microsoft.Visual.C++.11.0.x86"
