Here's how to configure Citrix v6.5 Pre-Launch or Instant App Access.
Login to your XenApp server and open Citrix AppCenter.
In Applications view right click on the application that you want to configure for pre-launch and select Other Tasks - Create pre-launch application.

You will notice that a new application will be created as in the picture below:
Have in mind that Application settings for Pre-Launch application are just copied from the Published Application. So, if you change anything for the Published application, you will also have to change this for the Pre-Launch application or just re-create Pre-Launch application.
To make sure this is working, try to login with test user and once you login to Web Interface server, you should automatically see a newly created session for Pre-Launch application.

Our Citrix users reported the following issues during the published application start:
The User Profile Service service failed the logon.
User profile cannot be loaded.
When I tried to login to the server using RDP I got the similar message:
Your user profile was not loaded correctly!
You have been logged on with the default profile for the system. Please see the event log for details or contact your administrator.

I have received the following error on my Citrix Receiver when I tried to run the published application:
Error number 2320, Citrix Receiver Configuration Manager: No value could be found for (AllowHotkey) that satisfies all lockdown requirements. The lockdown requirements in force may be conflicting.
Citrix Receiver was normally working, so I can't tell what has caused this behaviour.
I have tried to shutdown Citrix Receiver on my client machine and shutdown all other active Receiver processes, but without luck.
To solve this error a small registry change needs to be done.

On our new Citrix farm we had to strip Windows Explorer so our users couldn't access anything than network drives.
Therefore we wanted to remove the Favorites, Libraries and Network from the navigation pane.
By default, Windows Server 2008 R2 does not provides Group Policy to achieve this. Luckily, this can be done via Registry.
Note: Please backup the keys first.
To remove Favorites, please do the following:
First you need to take ownership of the ShellFolder before changing the value of Attributes.
Open registry editor and navigate to the following key.
