[Solved] VM working no more

[cesares]

I have installed VirtualBox 5.1.22r115126 on a Windows 10 Pro (64bit) machine with the latest major upgrade installed and I'm unable to run previously created VM.
I got the error that you can see on the attached log file.
Can somebody help me?

Thanks in advance

Cesare

Never seen "gown load" errors before. Try uninstalling Virtualbox, then rebooting the host, then re-install Virtualbox by right-clicking the Virtualbox installer program and choose "Run As Administrator" from the right-click menu, even if your account is an administrator account. (Note that "right-click-Run-As-Administrator" is not "log-off-log-back-on-as-Administrator-double-click", and it is not "I'm-already-an-Administrator-so-I-don't-have-to". Running the installer with a usual double-click under an Admin account will still not give you the necessary permissions.)

After that, look at this: Diagnosing VirtualBox Hardening Issues

Why the hardening log? Is there evidence that this was a hardening problem?

At a guess, from the wording I'd say that this is a problem with a saved state, which can be fixed by discarding the saved state (right click VM in manager, "Discard saved state"). The error would have been more obvious in the correct log.

I have attached the log specified in the pop up containing the error message

Thank you scottgus, reinstalling it as administrator solved the problem
