PA unable to sync spokenname with Unity
Symptom:
After upgrading PA to 1.3.3 or later, we are not able to sync spokennames with
Unity.
Condition:
Unity was not installed in default location.
Workaround:
Update the PAROOT/etc/VMBootstrap3.properties or
PAROOT/etc/VMBootstrap4.properties to point PA to the correct
location where Unity is installed. The property to be changed is
PROMPTS_DIR = \C$\Commserver\Stream Files
VMBootstrap3.properties is for a configuration with Unity 3.x
VMBootstrap4.properties is for a configuration with Unity 4.x
