A fully-automated, silent install for XenApp 6 Enterprise on Server 2008 R2.

01-install-xenapp-6.ps1

# This install assumes a couple things:
# 
# 1. You're logged in as a local admin, per Citrix recommendations
# 2. These script files are store in d:\software\citrix6
# 3. The installation media for XenApp 6 has been unpacked in d:\software\citrix6\citrix6
# 4. The MSIs for Hotfix Rollup 2 and Profile Manager are located in d:\software\citrix6\citrix6\addons 
#		(these can be excluded by skipping "04-01-install-patches.bat"
# 
# This install occurs across four reboots, and is complete unattended; you can kick it off 
# when logged in via RDP or at the console, and let it run to completion. Run time is 
# approximately 30 minutes, depending on your environment.

# NOTE: you should be logged in as a local admin, and use those credentials for these parameters

If you are still responding to this post..
Question: the script does the first part correctly installing XenApp It did not go to the next step of script 2 the config even though it was in runonceEX.. is the /103 not supposed to execute?? the Role Manager opens after the initial install and sits there nothing else.. Reboot and it does try to do config but doesn't execute the script successfully.

Any quick clues ??
