vRO 7.4 is not logging workflow runs and complaining of Lucene60

Just updated my home lab vra/vro from 7.3.1 to 7.4.0 . Installation seemed to go flawlessly, except vro.

When I try to run a workflow, the workflow completes, but nothing is in the log. When I look at the system log, I see:

2018-04-12 20:28:29.332-0500 [http-nio-127.0.0.1-8280-exec-6] WARN {} [StubbornRetrier] Retry 3/6 failed because of: Could not load codec "Lucene60". Did you forget to add lucene-backward-codecs.jar?
