Glad to hear that GOG is going well, even though you still have issues with languages.
As far as what Zorin did, I don't think Zorin did anything, other then include the Windows Program Loader, which is a component of WINE.
I forget which WINE version it was that I installed, but one of them comes with the Windows Program Loader. I just did a Google search, learned how to install it.
But hey, if it works in Terminal, that can't be all bad. AT least with terminal you can see if there are any errors. Only problem with launching GUI, is that GUI's don't usually provide error information unless an APP crashes lol.
