Citrix XenApp 6 for Windows 2008 R2 Tech Prev.

Here it is ! We were waiting for this one since few month now and Citrix just release the Technical Preview for XenApp on Microsoft Windows 2008 R2, XenApp 6.

Few things you need to know before beggining to test : Windows 2008 R2 is and will remain only 64bit OS. XenApp 6 can be install only on Windows 2008 R2.

I begin this insallation on a clean naked Windows 2008 R2 without any update. You can check teh system requirements here :

First, few screenshots of the new installation interface to describe the installation process.

DotNet 3.5 Sp1 is updated as soon as the installation beggins, after a new white interface very easy to understand popup and you can choose between reading some more information about what you’re going to install or adding roles to your server.

The installation kinda stop at this point, the Remote Desktop role required a reboot and the installation is unable to continue. A manual reboot needs to be done and the installation wizzard needs to be launch again. If one Citrix guy is reading that, these steps should be automatic, reboot + launch after reboot to continue the installion. So we do it again :

Because the kernel-mode drivers installed with this pre-release version of XenApp are not WHQL-certified, Windows displays a prompt before installing each driver, unless you do one of the following:

  • Before installing XenApp, add the Citrix VeriSign certificate to the trusted root store of the computer on which you are installing XenApp. You can copy the Citrix VeriSign certificate by viewing the properties of any XenApp binary file signed by the Citrix XenApp Server Certificate (for example, the autorun.exe file). This bypasses all WHQL-related prompts and enables you to perform an unattended installation.
  • While performing a wizard-based installation, select “Always trust software from Citrix Systems” when first prompted. This bypasses further WHQL-related prompts for the installation. [#224449]

Informations to fill are ‘classic’ for a XenApp installation, then the Datastore part, the is no more Local Access Database, now this is a least SQL Express database which is install during the installation process without any interraction on your Citrix XenApp6 server.

The following databases are supported for the data store:

  • SQL Server 2005 Express Edition, Service Pack 1
  • SQL Server 2008 Express Edition
  • Microsoft SQL Server
  • Oracle

This is it, now you need to reboot the server. You need to launch the configuration wizzard if you want to continue to configure the license server.

I had some trouble here while choosing the password for the ‘admin’ user, the network port 8082 seems to be already in use, I just change this value to 8083 and it did the trick, I think the service is already running on that port and we maybe have to stop the licensing service before trying to configure it.

We have a bunch of icons in the start menu, I will explorer everything in the next blog post.

The licensing server have a new friendly interface design, and as you can see the MMC is a bit different now and I must adminit I didn’t find everything (How to change the License server ? )

I will continue to post in the next blog what are the différences I notice between, XenApp 5 Windows 2008 and XenApp 6 Windows 2008 R2
