检测是否安装了Visual Studio 2013的Visual C ++ Redistributable

Question

如何检测Visual Studio 2013的Visual C ++ Redistributable是否已安装？

我使用Nullsoft NSIS安装程序系统但只需要Windows注册表项

我用Google搜索，并查看其他StackOverflow问题。特别是，这个Detect if Visual C++ Redistributable for Visual Studio 2012 is installed提供了要检查的确切注册表项，但是对于VS 2012的情况。

Answer 1

我的NSIS系统解决方案：

ReadRegDword $R1 HKLM "SOFTWARE\Wow6432Node\Microsoft\VisualStudio\12.0\VC\Runtimes\x64" "Installed"
ReadRegDword $R2 HKLM "SOFTWARE\Wow6432Node\Microsoft\VisualStudio\12.0\VC\Runtimes\x86" "Installed"
${If} $R1 != "1"
    ${AndIf} $R2 != "1"
        !insertmacro Log "Error: VisualStudio DLLs to the standard package (C++) 2013 is required!!"
        !insertmacro Log "Setup was not completed successfully."
        SetDetailsView show
        Abort 
    ${Else}
    !insertmacro Log "VisualStudio DLLs to the standard package (C++) 2013 is installed."

${EndIf}
