virtualbox.org

Hi all I have if you can lend a help please.
I am installing virtualbox and when intala not let me run get error attached image help please.

VirtualBox version?

p.s. That image could benefit from being a little larger, and compressed using PNG rather than JPEG.

Receiving this error after latest Win updates. Disabling Win Defender (AV) provided a workaround fix for me. I imagine this may be related to a similar error and issue fixed in 4.3.16 with other AV software.

Just for reference my host is Win8.1, virtualBox 4.3.18 (all guest OS's impacted, linux/win2003/7/2008/2012)

Hi mate versión
VirtualBox 4.3.18 for Windows hosts
I do not have antivirus system is windows 7
When I install it and just uninstalled virtualbox I run out conesion internet.

Try downgrading to 4.3.12, and follow the discussions going on the "security" sticky topic listed at the top of this forum.
