I have installed VirtualBox on my computer, in Fedora 26.
But impossible to launch it :
in a konsole, I read :
"VirtualBox: Error -610 in supR3HardenedMainInitRuntime!
VirtualBox: dlopen("/usr/lib64/virtualbox/VBoxRT.so",) failed: <NULL>
VirtualBox: Tip! It may help to reinstall VirtualBox."
Indeed, I have reinstall VirtualBox, after an entire update of my system.
But the error message don't change.
Thanks for your kind help !
