GameSpyJoin_MP_Demo.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like GameSpyJoin_MP_Demo.dll, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like dpnsvr.exe - to follow. These files were created so that multiple programs (eg. Battlefield 1942) could share the same GameSpyJoin_MP_Demo.dll file, saving valuable memory allocation, therefore making your computer run more efficiently.
Unfortunately, what makes DLL files so convenient and efficient, also makes them extremely vulnerable to problems. If something happens to a shared DLL file, either it goes missing or gets corrupted in some way, it can generate a "runtime" error message. Runtime is pretty self-explanatory; it means that these errors are triggered when GameSpyJoin_MP_Demo.dll is attempted to be loaded either when Battlefield 1942 is starting up, or in some cases already running. Some of the most common GameSpyJoin_MP_Demo.dll errors include:
- Access Violation at address - GameSpyJoin_MP_Demo.dll.
