PostgresSQL server failed

PostgresSQL server failed

I'm trying to upgrade an existing Win2008 ADAudit server and keep getting a information popup windows stating "Trying to start PostgresSQL sever failed at installation".  After which the ManageEngine service won't restart w/ a service-specific error Incorrect function.  Snapshot reversion fixed the second issue.  Suggestions for resolving the first issue so I can successfully upgrade?
