NS_ERROR_FAILURE (0x80004005) on all virtual machines

[KTK1990]

I haven't used Virtualbox in about a week, but when I tried to open any virtual machine today I received the error listed below. I am on the latest version of macOS Sierra (10.12.3 16D32) and on Virtualbox version 5.1.14 r112924 (Qt5.6.2)

--------

Failed to open a session for the virtual machine Windows10.

The virtual machine 'Windows10' has terminated unexpectedly during startup with exit code 1 (0x1).

Result Code: NS_ERROR_FAILURE (0x80004005)
Component: MachineWrap
Interface: IMachine {b2547866-a0a1-4391-8b86-6952d82efaa0}

• Open "VirtualBox-5.1.14-112924-OSX.dmg".
• Run "VirtualBox_Uninstall.tool". If there are any errors, please report them.
• Reboot.
• Re-install VirtualBox.

Moving to "OSX Hosts" from "OSX Guests" for obvious reasons.

Thank you for the quick reply and solution, it worked and I was able to boot up my VM after reinstalling and rebooting.

Sorry for posting in the wrong area, I saw Mac OS X and did not see the guest afterwards, Doh!

Great.
