Hello,
After installng, removing, new download and re=installing of version 4.3.4-91027, my virtualBox do not start. I have this error:

Het is niet gelukt een sessie te openen voor virtuele machine Win XP werkt.

VT-x is not available. (VERR_VMX_NO_VMX).

Resultaatcode:E_FAIL (0x80004005)
Component:Console
Interface:IConsole {8ab7c520-2442-4b66-8d74-4ff1e195d2b6}

This is a Win7 and in the box Win XP.
Pls, what can I do?
Thanks,
Tilia

See the 4.3.4 release discussion topic.

Thanks for Your answer. I am afraid I did not understand. From the given location I downloaded a fresh version.
I uninstalled the previous. And after installation I get the error.

The intention was for you to read the discussion, not download a new version. Note the "VBoxManage ... longmode" tip.
