如何才能使vcredist_x86重新安装只有在尚未安装？
在我inno安装运行select我强制无声安装MSVCRT。 我不知道如何使它自己安装只有在尚未安装？
这就是我现在所说的：
Filename: {tmp}\vcredist_x86.exe; Parameters: "/passive /Q:a /c:""msiexec /qb /i vcredist.msi"" "; StatusMsg: Installing 2010 RunTime... 由于您不想告诉您需要的Visual C ++可再发行组件包的最小版本，因此您可以在此获取可由您自己构build的代码示例。 请注意，我不知道哪个版本与哪些版本兼容，哪些版本必须安装，我会保留这个版本。
我唯一能告诉你的是你应该使用Check条件参数，当向导被打开时试图安装框架或运行库的解决scheme是错误的。 这个条件参数的作用是当你返回True时，文件正在被安装，如果False被跳过。 所以当你想安装你的运行时库时，你需要返回True到VCRedistNeedsInstall函数， VCRedistNeedsInstall返回False。 使用以VC_开头的常量的辅助函数VCVersionInstalled在安装包时返回True，否则返回False。
作为这个的来源，我使用了以下来源：
- 如何检测VC 8.0运行时可再发行组件包的存在
- 如何检测VC 9.0运行时可再发行组件包的存在
- 如何检测VC 2010运行时可再发行组件包的存在
下面的代码应该与Unicode和ANSI版本的Inno Setup兼容，这要归功于kobik的想法来使用条件定义 。

更新chuckleplant ：
增加了VC ++ 2012产品代码。 请注意，可再发行组件包会安装两件事情，即最小运行时间和附加运行时间。 对于您来说，查找最低运行时间应该就足够了。 对Microsoft Visual C ++ 2012 Redistributable产品代码进行testing将会给INSTALLSTATE_UNKNOWN ，请使用最小运行时代码。 VC ++ 2013和2015的情况也是如此。
您可以在HKEY_CLASSES_ROOT\Installer\Dependencies\find其他Visual Studio版本的产品代码，例如HKEY_CLASSES_ROOT\Installer\Dependencies\Microsoft.VS.VC_RuntimeAdditionalVSU_amd64,v14
更容易：
#define VCmsg "Installing Microsoft Visual C++ Redistributable...."

以下是使用Microsoft推荐的方法确定是否安装了VC Redistributable的版本。 我只需要VC 2015，所以你需要调整其他版本的值和参数：

Return true if later or equal to our 14.0.24212.00 redistributable // Note brackets required because of weird operator precendence Result := (major >= 14) and (minor >= 0) and (bld >= 24212) and (rbld >= 0) end; end; end; end; end;
