Install VCSA 6.7 appliance in Vmware Workstation 10

It's not deployed that way. It's not a bootable ISO!

You mount the ISO in an OS, and click the Installer. (and it then asks to be deployed to an ESXi server).

So it's not supported on VMware Workstation.

see here (for 6.5, but it's the same for 6.7)

HOW TO: Deploy and Install the VMware vCenter Server Appliance 6.5 (VCSA 6.5)

It is possible to Export/VMware Convert VCSA 6.7 from ESXi to VMware Workstation (with some work!) but it's not a supported activity.

you mean it needs to be installed inside of VM, for instance Windows ?
if so , is there any link to download an appliance in ovf format ?

you mean it needs to be installed inside of VM, for instance Windows ?

No. VCSA is a virtual appliance (a special time of VM)

if so , is there any link to download an appliance in ovf format ?

There is no OVF.

VCSA 6.7 (and all VCSA are delivered as an ISO).

You execute the installer on the ISO, and it gets deployed to an ESXi Host.

It will only function hosted on ESXi.

If you truly want to host it on VMware Workstation, it will need to be deployed as a VM, on ESXi (nested/installed in VMware Workstation)

(and that's another question).

So to Summaries your question

Install VCSA 6.7 appliance in Vmware Workstation 10

You cannot.

OK..
SO I need to install Windows Server VM, then install VCSA iso from within Windows server. Correct ?

Thank you
