Hi,
I did set the PATH to what you mentioned and tried to reboot the workstation. I was still stuck with the same issue.
The web client worked. And I had the same vCenter image copied onto another workstation and could login from it.
It looked like a problem with my system. But surprisingly I could login to vCenter from my vSphere Client now.
I don't know what solved the issue as I hadn't looked into it yesterday. I just tried logging in today and it worked!!!!
Thank you for all the help!!!!
Cheers,
Trupthi
