To address this issue, the CRT DLL is no longer considered a system file, therefore, distribute the CRT DLL with any application that relies on it. Because it is no longer a system component, install it in your applications Program Files directory with other application-specific code. This prevents your application from using other versions of the CRT library that may be installed on the system paths.
Visual C++ .NET 2003 or Visual C++ .NET 2002 installs the CRT DLL in the System32 directory on a development system. This is installed as a convenience for the developer. Otherwise, all projects that are built with Visual C++ that link with the shared CRT require a copy of the DLL in the build directory for debugging and execution. Visual C++ 2005 and Visual C++ 2008 install the CRT DLL as a Windows side-by-side assembly on Windows XP and later operating systems. Windows 2000 does not support side-by-side assemblies. On Windows 2000, the CRT DLL is installed in the System32 directory.
When you distribute applications that require the Shared CRT library in the CRT DLL, we recommend that you use the CRT.msm merge module that is included with Visual C++ instead of directly distributing the DLL file.
Windows side-by-side assembliesMsvcr80.dll with Visual C++ 2005 and Msvcr90.dll with Visual C++ 2008 are redistributed as Windows side-by-side assemblies except on Windows 2000. You should install these versions of the CRT on target computers by running the Vcredist_x86.exe application that is included with Visual Studio. There are installers for the x64 and IA-64 platforms also. Alternatively, you can use the CRT msm merge module that is supplied with Visual Studio to package the CRT installer into your own setup application. This will make the CRT available as a shared assembly to all applications because it is installed in the \windows\winsxs directory on supported operating systems.
