Installing Wine Mono on Windows is not a good idea, it'll interfere with .NET Framework stuff. Wine Gecko may be a better test case.
From what I understand, it's not really possible to create a .msi file that doesn't display any UI by default when run on Windows, but we'd probably want to disable that UI in the addon install code anyway.
You know on Windows when installing some apps, a window pops up saying configuring, preparing install or please wait. That's what WINE is missing. This app shows the dialog. http://www.microsoft.com/en-us/download/details.aspx?id=26347 It will show Please Wait and then it will change to configuring. Under WINE it shows nothing.
