SSAS instance required for March 2018 PBIRS

First, that's not a helpful response as there is no additional data in the error logs. That's part of the problem--this installation of power bi seems to leave out the necessary event id codes for the event viewer to tell us exactly what is happening with the error. perhaps you can tell us what Event ID 38 is exactly, since the software itself doesn't elucidate on that?

This is all that is shown for this error in the event log:

- <Event xmlns="http://schemas.microsoft.com/win/2004/08/events/event">
- <System>
  <Provider Name="MSOLAP$PBIRS" /> 
  <EventID Qualifiers="49441">38</EventID> 
  <Level>2</Level> 
  <Task>289</Task> 
  <Keywords>0x80000000000000</Keywords> 
  <TimeCreated SystemTime="2018-06-05T14:29:47.000000000Z" /> 
  <EventRecordID>95748</EventRecordID> 
  <Channel>Application</Channel> 
  <Computer>[redacted]</Computer> 
  <Security /> 
  </System>
  <EventData /> 
  </Event>

This error is raised immediately after the service is started, and only then.

What is event ID 38? Why didn't the PBIRS installation add the event data to the server? (There were no problems indicated in the installation).
