Remarks
You must specify either a Win32Path or a Win64Path, and can specify both. Generating and registering both 32-bit and 64-bit formats for a type library can improve performance if its interfaces are used from client processes of both 32-bit and 64-bit architectures.
For more information about type libraries and the attributes on this page, see Registering a Type Library.
