Thanks yanw for your reply I didn't uninstall v12 I upgraded existing v12 by running v14 installer and it did the job.when I opened it I noticed that VMNICs added by virtual Network editor of the VMware workstation are as it was except for VMNIC 1&2 I tried to add them again BUT they didn't appear also
I am just I will operate using another VMNICs I just want to figure out what happened and to be able to solve it in the future
