virtualbox.org

Hello.

I have a problem. When I run a virtualization Linux or Windows, this message appears :

"Échec de l'ouverture de session pour la machine virtuelle Test.

Unable to load R3 module C:\Program Files\Oracle\VirtualBox/VBoxDD.DLL (VBoxDD): GetLastError=1790 (VERR_UNRESOLVED_ERROR).

Code d'erreur : E_FAIL (0x80004005)
Composant : Console
Interface : IConsole {8ab7c520-2442-4b66-8d74-4ff1e195d2b6}"



Have you an idea of the problem? Thank you in advance!

PS : I'm French, and my computer turn in Windows 7

See: Minimum information needed for assistance. The interesting part is a zipped VBox.log. Attach it to your reply.

Oh sorry !

I have the last version of VirtualBox 64Bits (I suppose) : 4.3.20

And I have 4Go Memor.
My Windows 7 is 64bits also.

Take a look at the discussion: Windows 4.3.20 specifically for errors due to security. You might find some newer test builds and/or other helpful hints. It's a lot of things that cause this (antivirus, firewalls, debuggers, emulators, theme changers, etc). In your case I believe it's the Windows-theme-modifying program that you're running.

The linked thread also has a specific workaround for the case of the hacked uxtheme.dll.
