Installation error: "could not get preferred machine"

I’m installing Whonix for the first time and received this error message:

error: Failed to define domain from Whonix-Workstation-XFCE-16.0.5.3.xml
error: invalid argument: could not get preferred machine for /usr/bin/qemu-system-x86_64 type=kvm

Not sure what to do, not sure if I missed something.
