Citrix XenApp 6 Installation Pre-Requisite Environment

Important Notes Before Starting the XenApp 6 Installer:

1. Ensure the Windows server is genuinely licensed and fully activated
2. Ensure the Windows server is running with all the latest updates required
3. Ensure there is no pending reboot required for the server
4. Do not install XenApp on a domain controller. Citrix does not support installing XenApp on a domain controller
5. Do not join servers running XenApp 6 for Windows Server 2008 R2 to a deployment with servers running previous versions of XenApp
6. Citrix recommends using the latest Citrix License Server.
7. To ensure availability of the features and functionality of XenApp for Windows Server 2008 R2 to your users, install the most recent version of any plug-ins you use.
8. During a wizard-based installation, the XenApp Server Role Manager (using the Server Role Installer), automatically installs prerequisites for the selected roles.
9. For command-line installations, deploy the prerequisites before initiating XenApp role installation. Citrix recommends you deploy prerequisites (such as IIS role services) using the Microsoft ServerManagerCmd.exe command or Powershell, which Microsoft provides for Windows operating system roles.

Supported operating system: Microsoft Windows Server 2008 R2, except the Web Server  edition and the core installation option.

Minimum Hardware Specifications: Most servers running Microsoft Windows Server 2008 R2 meet the hardware requirements for XenApp

Installation Pre-requisite Software:  The XenApp Server Role Manager deploys the following software (except as noted), if it is not already installed:

1. .NET Framework 3.5 SP1 (this is a prerequisite for the XenApp Server Role Manager; it is deployed automatically when you choose to add the XenApp server role from the Autorun menu)
2. Windows Server Remote Desktop Services role (if you do not have this prerequisite installed, the Server Role Manager installs it and enables the RDP client connection option; you will be asked to restart the server and resume the installation when you log on again)
3. Windows Application Server role
4. Microsoft Visual C++ 2005 SP1 Redistributable (x64)
5. Microsoft Visual C++ 2008 SP1 Redistributable (x64)
6. If the server already has the following IIS role services installed, the Citrix XML Service IIS Integration component is selected by default in the wizard-based XenApp installation, and the Citrix XML Service and IIS share a port (default = 80).
7. If the IIS role services are not installed, the Citrix XML Service IIS Integration component is not selected by default in the wizard-based installation. In this case, if you select the checkbox, the Server Role Manager installs the following IIS role services.
8. If you do not install these services, the Citrix XML Service defaults to standalone mode with its own port settings, which you can configure using the XenApp Server Configuration Tool
   1. Web Server (IIS) > Common HTTP Features > Default Document (selecting this role service automatically selects Web Server (IIS) > Management Tools > Management Console, which is not required or checked for XenApp installation)
   2. Web Server (IIS) > Application Development > ASP.NET (selecting this role service automatically selects Web Server (IIS) > Application Development > .NET Extensibility; although not checked for XenApp installation, .NET Extensibility is required by ASP.NET)
   3. Web Server (IIS) > Application Development > ISAPI Extensions
   4. Web Server (IIS) > Application Development > ISAPI Filters
   5. Web Server (IIS) > Security > Windows Authentication
   6. Web Server (IIS) > Security > Request Filtering
   7. Web Server (IIS) > Management Tools > IIS 6 Management Compatibility (which includes IIS 6 Metabase Compatibility, IIS 6 WMI Compatibility, IIS 6 Scripting Tools, and IIS 6 Management Console)
9. If you plan to use Philips SpeechMike devices with XenApp, you may need to install drivers on the servers hosting sessions that record audio, before installing XenApp. For more information, see Citrix information on the Philips web site.
10. The XenApp Server Role Manager deploys the following software for installing Delivery Services Console, if it is not already installed:
    1. Microsoft .NET Framework 3.5 SP1
    2. Microsoft Windows Installer (MSI) 3.0
    3. Microsoft Windows Group Policy Management Console
    4. Microsoft Visual C++ 2005 SP1 Redistributable (x64)
    5. Microsoft Visual C++ 2008 SP1 Redistributable (x64)
    6. Microsoft Visual C++ 2008 SP1 Redistributable
    7. Microsoft Visual C++ 2005 SP1 Redistributable
    8. Microsoft Primary Interoperability Assemblies 2005
    9. If you already have the GPMC earlier version of the Delivery Services Console, you need to uninstall it and reinstall the Citrix XenApp Group Policy Management Experience (x64) program in order to use the GPMC to configure Citrix policies.
