Well, I managed to get it working, here's how:
1) In the VMware \ VMware VIX folder there is a file vixwrapper-config.txt. Make a backup and overwrite the following with the contents of the file:
#@Version-Info
2) If there is a folder called "Workstation-11.0.0-and-vSphere-6.0.0", move it somewhere else as a backup
3) Make a copy of the folder "Workstation-10.0.0-and-vSphere-5.5.0" and name it:
Workstation-11.0.0-and-Vsphere-6.0.0
4) Do not forget to add the vmrun path to the user variable: PATH (the vmrun path should look something like this: "C: \ Program Files (x86) \ VMware \ VMware VIX \")
Vmrun commands should now work.
The following command opens the virtual machine:
vmrun -T player start "D: \ myUser \ VMWare \ Windows7 \ Windows 7.vmx"
