Im trying to install BOINC and it uses Oracle VM Virtualbox 4.2.16, ive tried installing it 3 times and it keeps saying that it failed to install, it says The installation of Oracle VM Virtualbox 4.2.16 (x86) appears to have failed.

Whats going on, and how can i install it?

Their website (http://boinc.berkeley.edu/wiki/VirtualBox) says you can also install 4.2.16 by yourself, which may be necessary if you have to run the installer as Admin.
