I don't think winesetup needs big changes; I'm still not sure about what is broken. The attached file updates the registry shipped with winesetuptk to the current winedefault.reg, and also updates the dlls that are created when making a fake windows installation. As I've said, I'm not sure of what is broken, but if what has to go isn't determined by winesetuptk while running (Like the AppDefaults) then it's just a question of removing whatever has to go from the cfg_wine_without_windows.ini and/or cfg_wine_with_windows.ini. If anything else has to be changed, then Vincent should tell Alex what exactly has to change, so Alex can get on with it. This is presumably the quickest way of getting a working winesetuptk again, as he know Tcl/Tk very well. It's not worth wasting too much time on it, as were going to trash it soon, it doesn't matter if it can't tweak all aspects of the config file, it just has to make a working configuration for the user, that will often have to tweak the file by hand anyway until winecfg is ready.
