Environment
Upgrade from Retain 3 to Retain 4
Situation
After running the 4.0 installer to upgrade my software from Retain 3 to Retain 4 and after logging into the RetainServer web admin tool for the first time to have it update the schema, I restarted tomcat as instructed, logged into the RetainServer web admin again.

Resolution
We checked to see which ports were being used. Customer had McAfee installed on the Retain server and it was using port 8081, which is the one of the default ports used by the indexer.
Your options at this point are to change the indexer port from 8081 to something not in use or to remove the application using that port. In this case, the customer decided to remove McAfee.
