WebAPI Install Fail

I have a system with AF 2018 Server, PI DA 2018 and I am attempting to install PI Vision 2017 R2 SP1, which in turn installs PI WebAPI 2018.

During the setup of WebAPI, the configuration fails with the following error.



There is no indication of what fiile or folder it is looking at. I am guessing that it's the WebAPI folder under ProgramData\OSISoft that's the issue. The folder does exist and as an administrator I can open it - after I get the normal UAC message. WebAPI event log indicates "[Configuration]: Failed to persist configuration va;ues to local repository.


I have installed the WebAPI and Crawler services under the default "NT SERVICE\piwebapi" and "NT SERVICE\picrawler" at the moment.
