Visual Studio先决条件将安装已安装的程序包

Question

I am using VS 2015 where there is no prerequisite for Visual C++ Redistributable for visual studio 2012. So I created a custom bootstrapper and stored in the VS bootstrapping folder.

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>

Here is the product.xml

The setup downloads and installs the Visual c++ redistributable for visual studio 2012. But the problem is that even after it installs it, it I run the setup again it again downloads and tries to install the C++ redistribution. I thin the problem lies in the product.xml . Any way to resolve this??

Answer 1

After small research I found that "Visual C++ 2012 Runtime Libraries (x86)" has version 11.0, not 12.0 as you mention. Try this in your product.xml:

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