J'ai un current version of VirtualBox 4.3.20, but après the latest Windows 7 mise à jour on Dec. 11th, 2014, it cannot open any machine virtuelle. First, it would not ouvrez le programme du tout. Après a redémarrer, it would say:
STATUS_OBJECT_NAME_NOT_FOUND
Pilote is probably stuck stopping/starting. Essayez 'sc.exe query vboxdrv' to get more information about its state. Rebooting may en fait help. (rc=-101)
The log fichier says:
b28.146c: supR3HardenedVmProcessInit: Opening vboxdrv stub...
b28.146c: Error opening VBoxDrvStub: STATUS_OBJECT_NAME_NOT_FOUND
b28.146c: supR3HardenedWinReadErrorInfoDevice: NtCreateFile -> 0xc0000034
b28.146c: Error -101 in supR3HardenedWinReSpawn! (enmWhat=3)
b28.146c: NtCreateFile(\Device\VBoxDrvStub) failed: 0xc0000034 STATUS_OBJECT_NAME_NOT_FOUND (0 retries)
J'ai essayé l'installation an older version (4.3.18) également, reinstalling the current version several times, rebooting, uninstalling antivirus logiciel, but rien helped.
