The article Fedora virtualbox RC: NS_ERROR_FACTORY_NOT_REGISTERED advises the following actions:

yum  install  dkms
find /usr/lib/virtualbox -maxdepth 1 -name '*.so' -exec ln -s {} /usr/lib/virtualbox/components/
chown root.root /tmp
chmod ug-s /tmp
chmod 1777 /tmp

A very similar bug-report, although old one, is OSE / Hardened: NS_ERROR_FACTORY_NOT_REGISTERED => Fix symlinks.

The solution here is to add the following symlinks:

cd /usr/lib64/virtualbox/component
ln -s ../ .
ln -s ../ .
ln -s ../ .
ln -s ../ .
ln -s ../ .

Then restart VirtualBox.

If I understood right the comments, the problem arises when the bin/ directory was moved.
