I convert my com Out-Proc project from CComSingleThreadModel to be CComMultiThreadModel.
(ThreadingModel = Free).
This out-proc calls an in-proc project (multiThreaded as well), this in-proc tries to CoCreateInstance of ShellLink interface.
Since the conversion the CoCreateInstance of ShellLink interface failed, the error I recieve is -2147467262 ("no such interface supported").
(Just for testing, I make my out-proc to be a SingleThreaded again and it worked fine).
What should I do to make it work in MultiThreaded as well ?
