I think a good solution would be to add code to wine to offer to download it and install when it is needed.
That should be only a few lines of code using MessageBox() and URLDownloadToFileW()... something like the following patch, but perhaps with a progress bar, and internationalized messages?
Hey yes, that's a fantastic idea! It doesn't generalize to the other cases for the Moz ActiveX control that would work wonderfully. Let's do it! :)
