Installing XENApp 6 Fundamentals recently, the installer would through an error when adding the Citrix Licensing component. Looking at the Citrix Access Essentials Installer log under C:\Users\%USERNAME%\AppData\Local\Citrix was the following error:
“failed to configure component citrix licensing”
The installer will fail if the user does not run as Administrator AND any Licensing Service components should be removed before trying again. Removing the service in Add/Remove Programs and then restarting the installer with RunAs Administrator then allowed the installation to continue.
