10144	windows guest additions broken in 4.1.8	matteo sisti sette		"I've upgraded to 4.1.8 (ubuntu 11.10 host, windows 7 guest) from 4.0.12

I have tried to install guest additions on the guest.
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
