It picture will messes up if I move the windows around the desktop. So I though it might be lack of WineD3D and so I installed it from wined3d.iso. Then it messed up my guest XP. Now I cannot even play and videos which I could before and it says Direct3D is not enable when I do this "dxdiag" in the RUN command. > > Can you guys please help? I saw i digged a lot in foruns... Wined3d in VirtualBox crashes a lot of applications (like autocad), so there shoud be a simpler way to uninstall it. hopefully, wined3d installation gives a full log, so if you want to uninstall just install again and check up que install log on the Details on install screen... here is a way to uninstall wine d3d 8 and 9 in a batch script: Wined3d_Uninstall.bat Code: del C:\WINDOWS\system32\libwine.dll del C:\WINDOWS\system32\wined3d.dll del C:\WINDOWS\SysWOW64\libwine.dll del C:\WINDOWS\SysWOW64\wined3d.dll del C:\WINDOWS\system32\d3d8.dll del C:\WINDOWS\system32\d3d8_test.exe ren C:\WINDOWS\system32\d3d8.dll_backup_by_wined3 dd3d8.dll del C:\WINDOWS\system32\d3d9.dll del C:\WINDOWS\system32\d3d9_test.exe ren C:\WINDOWS\system32\d3d9.dll_backup_by_wined3d d3d9.dll pause Hope it solves it for you Pastorelli
