Cannot connect to vCenter through the Streamed VM Setup Wizard in order to create Virtual Machines (VMs).
To resolve this issue, complete the following steps:
Caution! Refer to the Disclaimer at the end of this article before using Registry Editor.
Back up the registry on the Target Device and create a registry key named PlatformESX under HKLM\Software\Citrix\ProvisioningServices.
Under PlatformESX, create a string value named Datacenter and then type the name of the datacenter where the virtual machine targets are hosted.
When multiple Datacenters exist within vCenter, the wizard might fail to enumerate the hosts in the cluster that the user is trying to use, causing the wizard to fail with the following error message:
“Cannot connect to the hypervisor at <hypervisor_name>: Object referenced not set to an instance of an object.”
