When you install using the AUR script - the last lines should look like this
==> Before using VMware, you need to reboot or load vmw_vmci and vmmon kernel modules (in a terminal on root: modprobe -a vmw_vmci vmmon)
==> You may also need to enable some of these services:
- vmware-networks.service: to have network access inside VMs
- vmware-usbarbitrator.service: to connect USB devices inside VMs

These are the instructions to get VMware working.
modprobe -a vmw_vmci vmmon
If you need the vm to have network access (add --enable) if you want any of the service to start at boot.
systemctl enable vmware-networks
If you need to pass on USB device into the vm
systemctl enable vmware-usbarbitrator
If that doesn’t do it you need to contact vmware support - after all it is a paid service - but as I said Arch based distribution are unsupported by VMware.
