"Could not open /dev/vmmon" on macOS 10.12

Hi,

I am currently on Fusion 8.5.0 freshly downloaded from your website. I have a couple of VMs from before I upgraded my OS to 10.12. Now none of them will start/resume and all I get is the error in the title.

I upgraded to Fusion 8.5.0 before the OS update and it worked fine, so I guess something in the OS update broke it.

I have tried searching around in this forum and have tried the following to no avail:

1. uninstall/reinstall
2. reboot
3. install a new VM from image

In case it helps, I do have VirtualBox installed as well, and I need it just as much as I need Fusion.
