Customization of Windows guests fails with the error: Customization of the guest operating system 'windows7Server64Guest' is not supported in this configuration

Today when one of my client was deploying the vm from template then it was failed with this error message 
"Customization of Windows guests fails with the error: Customization of the guest operating system 'windows7Server64Guest' is not supported in this configuration" 


Possible Causes:-
1. VMware tools are not installed in the source VM or Template. Install VMware tools or Upgrade VMware Tools
2. vCenter is not running with the correct version that can support the OS version. Upgrade your vCenter.
3. In NFS datastore "no root squash" is not enabled. Enable it.

Root Cause in my environment:-
VMware Tools were not installed.
