An error message, which pops up during a system malfunction is an information sent to the user by the computer. In short, it holds the details necessary to let the user comprehend why and how this malfunction occurred. Since, computers aren't self-sufficient to solve many error instances, through error messages they demand user involvement.
However, the error messages are very much technical which will be incomprehensible for the regular user. Hence a little familiarity with error codes can be helpful in understanding how to solve them. Here are some examples of error messages involving missing DLLs which should help you to shine some light on this matter.
