Symtom:

When trying to deploy a desktop using VMware View (Horizon), you receive the following error in your connection server:

Mar 31, 2013 1:41:45 PM CDT: View Composer agent initialization state error (16): Failed to activate license (waited 1215 seconds)

Solution:

This error is caused by Windows not being activated.  To solve this error, make sure you have Windows Activated or that Windows can properly reach your KMS server to activate Windows.  Once the OS is activated, simply restart the VMware Agent service or reboot the machine to have your vconnect server set the desktop to available.
