Demo with CoCreateInstance and explicitely specified architecture

I tried 
=====================================================================================
IServerWrapperPtr ptr = NULL;
HRESULT hr = CoCreateInstance(__uuidof(ServerWrapper),
                NULL,
                CLSCTX_LOCAL_SERVER | CLSCTX_ACTIVATE_32_BIT_SERVER,
                __uuidof(IServerWrapperPtr),
                reinterpret_cast<void**>(&ptr));
=====================================================================================
(please find attacted "ClientModified_001.cpp" and the accordingly built
"ClientModified_x64_001.exe") 
where I explicitely specified architecture. 

This works fine on Windows but on Wine the result is still REGDB_E_CLASSNOTREG
= 0x80040154L

Or do I do something wrong here (additional flags required)?
Please let me know if there is a way in the current Wine-4.0 where it may work
or confirm the bug report.

If there is anything more that I can provide, please let me know.

Again, many thx for immediately providing comments.
