为客户部署哪个 msvcp100.dll/msvcr100.dll？

Question

With my product I have deployed specific versions of msvcp100.dll and msvcr100.dll that also belong to a redistribution package. To be more precise, I use them from my directory C:\\Program Files (x86)\\Microsoft Visual Studio 10.0\\VC\\redist\\x86\\Microsoft.VC100.CRT . I just put these dlls into the installation directory of my software. And yes, my software is compiled as x86 and with Visual Studio 2010.

Those work fine on my machine. However, I see that some customers get errors that can be solved by removing those files and manually installing the Visual Studio 2010 redistributables with the online installer from Microsoft. The errors will be of the form:

This application has failed to start because MSVCR100.dll was not found. Re-installing the application may fix this problem.

I thought that msvcp100.dll and msvcr100.dll are in some kind unique but there seem to be different version to be out there. How should I deploy these files to my customers such that it works for all of them? If this is not possible, what would be a good way to deploy these files?

这取决于操作系统版本和体系结构，因此最好在安装程序中添加 Microsoft Visual C++ Redistributable Package 作为先决条件，以便安装程序可以检查系统是否确实需要，然后相应地安装/跳过它。
