openHistorian configuration stops during initial setup

I am trying to configure openHistorian on a new machine. It is version 2.8.157 and running a MySQL database (v8.3.0.0).

In the configuration it gets up to the step “Attempting to set up the initial historian” and then stops with this error message:
“Object reference not set to an instance of an object”

At this point I can’t resume and have to try and run the process again, but it always crashes at this point.


Can you try setting up with SQLite DB - this requires no external database dependencies. Can always upgrade later using the database migration utility. My guess is the version of MySQL ConnectorNET is not working or is not a version we support.
