在我的 inno setup RUN 选择中，我强制静默安装 MSVCRT。我想知道如何让它在尚未安装的情况下自行安装？
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什么最小版本的 Visual C++ 可再发行程序包，这里有代码示例，您可以根据它自己构建它。请注意，我不知道，什么版本与什么兼容，必须安装什么低版本，我会一直告诉你的。
我唯一可以告诉你的是，你绝对应该使用Check 条件参数，在打开向导时尝试安装框架或运行时库的解决方案是错误的。此条件参数的工作方式与您返回 True 时一样，正在安装文件，如果为 False，则跳过它。因此，当您想要安装运行时库时，您需要将 True 返回到 VCRedistNeedsInstall 函数，否则返回 False。此处使用以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。
作为本文的来源，我使用了以下来源：
感谢kobik's idea to use the conditional define，以下代码应该与 Unicode 和 ANSI 版本的 Inno Setup 兼容。

更新chuckleplant：
添加了 VC++ 2012 产品代码。请注意，可再发行包安装了两个东西，最小运行时和附加运行时。寻找最小运行时间应该就足够了。针对 Microsoft Visual C++ 2012 Redistributable 产品代码进行测试将给出 INSTALLSTATE_UNKNOWN，请改用最小运行时代码。 VC++ 2013 和 2015 也是同样的情况。

我知道这是一个非常古老的问题，但我遇到了这种情况，因为我无法进行 winregistry 检查，所以我采用了这种方法，
基于此文件列表：https://matthew-brett.github.io/pydagogue/_sources/python_msvc.rst.txt
我能够检查文件是否存在，例如 VCRedist 2015/2013 x86/x64：
2015
C:/Windows/System32/msvcp140.dll - x64
C:/Windows/SysWOW64/msvcp140.dll" - x86
2013
C:/Windows/System32/msvcp120.dll - x64

【讨论】：
Comsci's answer（Martin's answer 改编）很接近，但没有正确执行版本检查。 （例如，如果次要版本中有一个凸起并且内部版本号重置为零，它将失败。）这是该答案的更正版本，适用于 32 位和 64 位 Visual Studio 2015-2019 软件包。
我发现当前的 64 位软件包如果已经安装会破坏运行时，所以在安装之前检查是必要的（直到微软修复了这个问题）。编辑：这可能已在 Visual Studio 16.10 (release notes) 中修复。
与原始答案一样，这是基于Microsoft recommended way of determining whether the VC Redistributable is installed。
