我一直试图解决这个错误很长一段时间，我已经尝试在线下载32位和64位的MSVCP120D.dlll文件。我已经尝试将32位文件放入System32文件，将64位文件放入SysWOW64文件中，但这并不能解决错误。任何形式的帮助将不胜感激，谢谢。

Answer 1

MSVCP120 D .dll是 debug C / C ++运行时的一部分。您仅在调试版本中获得对该库的依赖性。通常，您不应该分发调试版本，因此您不需要该库。

如果您进行发布版本，则它将取决于MSVCP120.dll，您可以通过安装Visual Studio redistributable package来获取该版本。请注意，MSVCP120.dll是Visual Studio 2013的一部分，而不是您提到的2017年，所以我链接VS2013版本。除此之外，Microsoft将这些DLL捆绑为Visual Studio安装的一部分，以防您希望随软件一起分发它们。在我的机器上，它们位于C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\redist\x64\Microsoft.VC120.CRT。使用较新版本的Visual Studio，只需将这些DLL放在可执行文件旁边即可。对于早期版本，您可以将包含文件夹Microsoft.VC???.CRT放在可执行文件旁边。

最后，即使您不应该重新分发调试CRT DLL，Microsoft仍然将它们作为Visual Studio安装的一部分包含在内。在我的机器上，它们位于C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\redist\Debug_NonRedist\x64\Microsoft.VC120.DebugCRT

您的计算机错误VS2017中缺少C ++ MSVCP120D.dlll
