Regsvr64 is a developer tool that simplifies registration of COM DLLs across platforms.
The tool will identify the bitness of a DLL file and register it correctly. If the tool is on a 32-bit system and a 64-bit DLL is passed, it is simply ignored.
Works on Windows XP or later.Note:
this tool is intended for developers
to be used locally or shipped with their source code projects. End-users will most likely not have any use for it.
