--- Comment #12 from Cùran debian@carbon-project.org 2010-06-01 07:01:17 --- The demos I've found (e.g. [0]) don't show the problem, but they don't have the themed installer like you can see in attachment 23465 or attachment 24349 either. They use the "default" Windows MSI installer (GUI wise) AFAICT. And other "normal" MSI installers work too, so it doesn't seem surprising that the demo installer works.
But maybe you can tell me which debugging facilities you'd like to have or if I should run Wine with gdb or strace or something like that.
