1] Re-register the DLL file
As you can see, the file extension of the software that’s throwing up this error is a Dynamic Link Library (dll) file. A dynamic-link library (DLL) is a module that contains functions and data that can be used by other modules (applications or DLL). DLLs provide a way to modularize applications so that their functionality can be updated and reused more easily. DLLs also help reduce memory overhead when several applications use the same functionality at the same time because although each application receives its own copy of the DLL data, the applications share the DLL code.
