Two things won't work.
1. SAPI5 Voices.
2. Watch Clipboard
When I try running the program in terminal and use a SAPI5 voice, I get this:
err:ole:marshal_object couldn't get IPSFactory buffer for interface {2baeef81-2ca3-4331-98f3-26ec5abefb03} err:ole:StdMarshalImpl_MarshalInterface Failed to create ifstub, hres=0x80040155 err:ole:CoMarshalInterface Failed to marshal the interface {2baeef81-2ca3-4331-98f3-26ec5abefb03}, 80040155 fixme:ole:NdrClearOutParameters (0x251e6f0,0x7e3e88a0,0x251e91c): stub fixme:ole:CoCreateInstance no instance created for interface {2baeef81-2ca3-4331-98f3-26ec5abefb03} of class {96749373-3391-11d2-9ee3-00c04f797396}, hres is 0x80040155
I showed this to someone, who said: "IIRC, it is because the 32-bit package is not multi-arch and can't be installed along with a 64-bit version." ... "Since the app is freeware, you should ask for help at the winehq forums where somebody knowledgeable can run a debug trace on it and see where the problem is."
And here I am!

Let me know if there's anything else you need from me. I'll be here!
