I checked ""Direct 3D support"". I got a dialog informing me that support for some feature (Windows Aero or something like that) is experimental, and asking whether I wanted to ""install basic 3d support instead"" I chose No (I want the experimental full-featured support). Then I got more or less the following error message (I have to write it by memory): ""A corrupt version of Direct 3D has been detected. Installation cannot continue and will be aborted"" Indeed, the installation wizard then hanged forever and never even finished aborting. So I cannot install the latest guest additions. Btw, I seem to remember that formerly, in order to install direct 3D support you had to restart windows in safe mode, but you got a warning telling you the steps to follow when trying to intall the guest additions in normal mode, and I haven't seen such a thing now.",defect,closed,guest additions,VirtualBox 4.1.8,obsolete,,,Windows,Linux
