Try to upgrade workstation from 12.0 to 12.5. Then choose VMware ESX v.6 during VM creation.
Please check the VM's configuration (.vmx) file and add/edit the following line for each network adapter:
ethernet#.virtualDev = "vmxnet3"
(where # represents the adapter's number)
Make sure you do this with either VMware Workstation - or at least the VM's tab - closed to ensure the configuration is re-read after the manual modification.
Alternatively, add the network adapter after the VM has been created.
