vmrun -T player start : Error: Unknown Error 2.6.32-573.el6.x86_64

Hi,

I am running the following system:

2.6.32-573.el6.x86_64

VMWare Player 12.1.1-3770994.x86_64

The issue I am having is that I can start the VM through the GUI no problem using "vmplayer" as root however when I try to do vmrun -T player start /path/to/vm.vmx nogui I get the response "Error: Unknown error" with no log entries appearing in vmware.log to provide insight as to whats happening. I have tried the below solution which seems to solve it for others but this is not working for me:

Re: After install kernel 2.6.32-504 Could not open /dev/vmmon

I can follow all steps without errors for all suggested solutions in that thread all the way to the end and it still fails to run. Really frustrated here and not sure where to look next, any help or pointers anyone could provide would make my day .... :-(

Thanks,
