Hey Ilian,
we have installed the vCenter Orchestrator on the same server, as vCenter Server is installed.
I also looked on the ISO-File, from which we installed all the vCenter components (including vCenter),
but I couldn't find any files or installation package for the vCenter Orchestrator Client.
Rigth now, I start the following application from the vCenter Server:
"C:\Program Files\VMware\Infrastructure\Orchestrator\apps\vCenter Orchestrator Client.exe"
I would like to install this client on my workstation, but I don't know where I can get the installation package.
