First I will explain what is a DLL file and it's uses. Then I will give the solution to the above type of dll error messages.

A dynamic-link library (DLL) is a module that contain functions and data that can be used by another module. Module can be another DLL or a Windows application. A DLL can be used by several programs at the same time. Windows operating system provides some DLLs. Some DLLs are particularly written for a application and these DLLs are loaded with that particular application.

DLLs save memory, reduce swapping, save disk space, upgrade easier, provide after-market support, provide a mechanism to extend the MFC library classes, support multilanguage programs, and ease the creation of international versions. DLL file will be loaded in to RAM when a program needs it only. Thus DLLs save memory. It saves Disk space since same DLL is used by several applications. If each application has it's own DLL then a lot of space is required.
