--- Comment #2 from Rosanne DiMesio dimesio@earthlink.net 2010-12-12 22:26:48 CST --- I still have the wineprefix that I got to work by not installing Outlook, and that one still works--Word, Excel, and Powerpoint all start up without setup.exe starting. But now I'm unable to reproduce that in another wineprefix; as you say, the installer starts even without Outlook installed. I'm not sure what's going on.
