The idea is that a DLL is not just identified by a name, but by a number
(the CLSID). The CLSID is stored in the registry and is looked up to get
the fully qualified path of the DLL. The rules of COM specified that the
CLSID should change whenever the version of the DLL changed.
Unfortunately, developers broke this rule, so DLL hell persisted. But if
the developer i honest and complies with this, COM does not not produce
DLL Hell.
