Best practice for harvesting COM file file to WiX fragment

I have made a dynamic deployment project based on WiX 3.0, that uses mainly HEAT to consume directories in dynamic way (files + DLL that need to be registered).

The question is that i don't understand开发者_高级运维 what attribute should i use in heat in term of the COM, Should i use "-SCOM" or not (what does it effect e.g. patching)

thanks

heat.exe automatically harvests self registration from DLLs when harvesting directories. heat.exe does not currently support capturing self registering executables.
