virtualbox.org

During the installation of VirtualBox 4.3.24 on a PC with Windows OS 8.1 is becoming the message:
SYSTEM_THREAD_EXCEPTION_NOT_HANDLED (ndis.sys).
Can you help?
What do I do?
Thanks

Well I did a quick search (you know, Google) and I came up with this: viewtopic.php?f=6&t=64397
See if it helps you. Otherwise do a search for "SYSTEM_THREAD_EXCEPTION_NOT_HANDLED (ndis.sys) site:forums.virtualbox.org" and see if you can find something more relevant.
