Well, because I don't have this installed, the client program you linked to wanted to download and install the server component when I ran it. I knew this was going to happen, because I went to the actual site rather than just accepting a download link of an unknown application.
The window for the secondary download did open, but did not render fully-- only the titlebar of both windows and the button of the child window rendered, the mdi interior of both the main and child windows did not, and no text at all was displayed. As I said, I suspect that had this additional download not been necessary (because I had previously installed both parts of the program under Windows), that it might well have worked (since the render of the windows actually went quite well for a Wine app, and indicated that the problem was perhaps not with the program itself, but with this additional connection to the Internet and secondary installation, which might well be more than what Wine is prepared to deal with).
I have no interest in installing this program under Windows (sorry
) so I am not going to test that theory, but I did provide my output in case it makes more sense to the developers of Wine who frequent the wine-users mailing list than it makes to me.
But at this point, I don't have enough information about whether the program runs at all when fully installed to advise you on whether the problem is with your configuration, or with the program itself, so I pointed you to those who would better be able to gather that information than I am.
