I have designed two powershell based scripts which would install xenapp 6 completely(ie., prerequisites and xenapp6 setup). Just point the script to your xenapp folder. It will take care of the rest. After the first script is completed, create a dsn(file dsn) to connect to your database and change the username, password,dsn file location etc in the script and run it. XenApp6 will be installed. All the prerequisites along with required windows roles and features, sql express 2008 express will be installed.

Prerequisites

Run the InstallPrerequisites.ps1 file. After it is installed, it will reboot. create a file dsn to connect to your database. Enable tcp/ip and start sql server browser service and restart sql services Run the InstallXenApp6.ps1 file.

Now your system will be restarted again and XenApp6 is installed successfully. You can use XenApp6 now. After reboot configure your license server and webinterface.

Enjoy!!!

Make sure you meet the below requirements:

1. Set Executionpolicy to remotesigned.
2. At installing xenapp or licensing or web interface steps, if you notice that you are not able to see any next steps after long time, press space to refresh the console. Dont press Enter key. You will be prompted to enter farm details later and if you press enter, empty value will be keyed in. So press space only.
3. SQL will be installed as builtin\administrators group ie., Local admins group in the server where sql is installed.

Details I used: odbcusername:administrator odbcpassword:local username pwd

When you download the scripts from the below links, make sure that you right click on each script and unblock them.

Scripts are available here: InstallXenApp6_Ver 0 and InstallXenApp6Prerequisites
