This was a fresh installation of the software and VirtualBox gives me this error message after starting a virtual machine I created:
Failed to open a session for the virtual machine PinkiePie.
The virtual machine 'PinkiePie' has terminated unexpectedly during startup with exit code 1 (0x1). More details may be available in 'C:\Users\Kobe\VirtualBox VMs\PinkiePie\Logs\VBoxHardening.log'.
Result Code: E_FAIL (0x80004005)
Component: MachineWrap
Interface: IMachine {f30138d4-e5ea-4b3a-8858-a059de4c93fd}
I tried uninstalling it, installed older builds of it, downloaded certain dlls some forums suggested but to no avail.
