During installation or upgrade you notice the installer is hung at:
"Checking startup status of Storage Engine nodes"
You also notice the Query Engine Service Starts then stops if started manually during this state.
WORKAROUND
1. Disable one of the NICs on the Unified Communications Analytics (UCA) machine.
Note: If you have two UCA machines with two or more NICs enabled on each you would want to disable all but one
2. You can re-enable the additional NICs if required after the installation is complete.
STATUS
Waiting for fix in a future release of Unified Communications Analytics
