如何让vcredist_x86只在尚未安装的情况下重新安装？

在我inno安装运行选择我强制无声安装MSVCRT。我不知道如何使它只在尚未安装的情况下进行安装？如何让vcredist_x86只在尚未安装的情况下重新安装？

这就是我现在拨打：

Filename: {tmp}\vcredist_x86.exe; Parameters: "/passive /Q:a /c:""msiexec /qb /i vcredist.msi"" "; StatusMsg: Installing 2010 RunTime...

东西已经被问['here'（http://stackoverflow.com/q/10982468/960757），但是我不同意答案，因为它在向导启动时安装框架，但是当您按下最后一个*下一个*按钮并开始安装时，应该运行IMO。我将尝试查找此检查所需的注册表项。在此期间看看['这篇文章']（http://stackoverflow.com/a/10111173/960757）。您需要为此使用['Check']（http://www.jrsoftware.org/ishelp/topic_scriptcheck.htm）参数。 – TLama

既然你不想告诉什么最低版本的Visual C++，你需要再发行组件包，在这里你的代码样本，从中可以通过建立这个你自己。请注意，我不知道哪些版本与哪些版本兼容，以及必须安装哪些较低版本，我会保留这一点。

我唯一能告诉你的是，你应该肯定使用Check条件参数，当向导打开时试图安装框架或运行时库的解决方案是错误的。这个条件参数的作用就像当你返回True时，文件正在被安装，如果False它被跳过。所以当你想安装你的运行库时，你需要返回True到VCRedistNeedsInstall函数，否则返回False。使用以VC_开头的常量的帮助函数VCVersionInstalled在安装软件包时返回True，否则返回False。

由于这个我用以下资源来源：

下面的代码应与Unicode和ANSI版本兼容Inno Setup安装感谢kobik's idea to use the conditional define。

更新由chuckleplant：

添加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。它应该足以让您查找最小运行时间。针对Microsoft Visual C++ 2012 Redistributable产品代码进行测试将给出INSTALLSTATE_UNKNOWN，请改为使用最小运行时代码。它是VC++ 2013相同的情况和2015年

你可以找到在HKEY_CLASSES_ROOT\Installer\Dependencies\其他Visual Studio版本的产品代码，例如HKEY_CLASSES_ROOT\Installer\Dependencies\Microsoft.VS.VC_RuntimeAdditionalVSU_amd64,v14

非常感谢您提供这样的格栅答案！ – myWallJSON

请注意，有时即使OS包含“VC++运行时”，也不足以满足您的应用程序;偶尔服务包或修补程序会安装在您的开发人员电脑上，最终需要比最初随OS提供的更高版本的运行时间。因此，不要忘记在您的开发/构建PC上安装更新后，始终在“干净的”PC/VM上测试您的应用程序。 – Miral

@TLama：此代码适用于'VC_2008_REDIST_X86'，但不适用于'VC_2008_SP1_REDIST_X86'。它始终安装VVisual C++ 2008 SP1可再发行组件包（x86）。你能帮我么？ – Shoshi

它看到ms最新的msvc 2015 redist被标记为“Microsoft Visual C++ 2015 x64 Minimum Runtime - 14.0.23026”，因此字符串中不会出现“Redistributable”字样。 –

下面是一个使用该版本Microsoft建议确定是否安装了VC Redistributable。我只需要VC 2015年，所以你需要为其他版本的适应值和参数：类似
