Wine missing COM Component from mfwmaaec.dll - {745057c7-f353-4f2d-a7ee-58434477730e} not registered

Hi friends! Recently I run on error when trying to launch my application developed on Unity (with Windows 10,11 compatible SDK). Finally from many errors in console I have the last ones which is:

01b4:err:ole:com_get_class_object class {745057c7-f353-4f2d-a7ee-58434477730e} not registered
01b4:err:ole:com_get_class_object no class object {745057c7-f353-4f2d-a7ee-58434477730e} could be created for context 0x1

There is some wiki how to cope with that:

Since I am not expert can someone please share step by step what to do? Until now, I know that from native Windows this ComObject is located in C:\Windows\System32\mfwmaaec.dll or C:\Windows\SysWOW64\MFWMAAEC.DLL

Also winetricks lacks this .dll

It could be something else, you can try giving us a bit more context. If nothing else helps you can try finding MFWMAAEC.DLL from somewhere (your Windows installation?) and registering it as a COM server with regsvr32 but I really really doubt that's the actual reason.
