In computing, DLL Hell is a term for the complications which arise when one works with dynamic-link library (DLLs) used with Microsoft Windows operating systems, particularly legacy 16-bit versions, which all work in a individual memory space. DLL Hell can manifest itself in many different ways wherein applications neither launch nor work correctly.

COMING SOON!
