10071	"The checkbox  for ""Enable 3D Acceleration"" is deactivated in the VM settings & ""Your Direct X driver is corrupt or incorrect"" message ==> Fixed in SVN"	procyon777		"I have Windows XP 32bit as a host OS, and installed Windows 7 64bit as a guest OS. Everything (including AERO) was working fine with VB 4.1.6, but I got the ""Your Direct X driver is corrupt or incorrect"" problem when I upgrad into VB 4.1.8 and install the Guest Additions. When installing the WDDM driver (not basic direct3D), I keep getting the error message ""Your Direct X driver is corrupt or incorrect. The installation cannot continue. For more information please check the VB manual""

I uninstalled all guest editions in safe mode and reinstalled it in safe mode as well, but the problem still exists. The weird thing I noticed is that ""the checkbox"" for enabling 3D acceleration is deactivated in the VM settings. I can not change any settings for 3D acceleration with VM 4.1.8. 2D acceleration setting is fine. I also have Ubuntu 10.10 VM, and ""the checkbox"" for 3D acceleration is deactivated for Ubuntu too. It may be a systematic bug of VM 4.1.8 itself, not guest OSes.

Finally reinstalling the VB 4.1.6 solved the problem. Now everything works like a charm with VB 4.1.6.

I have AMD Radeon HD 5750 as a main graphic card, and the latest version (11.12) of AMD Calatyst was installed. My CPU is AMD phenom II x4 965."	defect	closed	3D support	VirtualBox 4.1.8	fixed	DirectX, 3D, checkbox		Windows	Windows
