Oct 03, 2017

You can use Citrix App Layering in virtually any hypervisor environment, but it is designed to support the hypervisors, provisioning services, connection brokers, and Windows operating systems listed below. You also need a browser that supports Microsoft Silverlight. 

The Enterprise Layer Manager (ELM), hereafter referred to as the App Layering "appliance," is a virtual appliance that runs on your hypervisor.  Once installed, you can configure the appliance, and begin creating layers.

Hypervisors for the Citrix App Layering appliance

The App Layering appliance and Connectors, run in the following environments:

  • Citrix XenServer 6.5, 7.0, 7.1, 7.2
  • Azure Resource Manager
  • Microsoft Hyper-V running on Windows Server 2012 R2 or Windows Server 2016
  • Nutanix Acropolis
  • vSphere vCenter 5.5.x, 6.0.x, 6.5.x

App Layering supports single-byte language packs for the base US English Windows operating system. Install the language packs on the operating system machine before importing the operating system into a layer. Language packs installed on a version added to the OS layer do not work correctly.
