On my MacBook Pro, OS 10.11.6:
I just installed LibreOffice 6.1.5.2, and tried to enable the extension Writer2Latex, which I have used before in previous versions. When I click on the enable button, I get the error message is “Could not create Java implementation loader” . I think this has to do with configuring to find the current Java runtime, but I don’t see where to do that. A message about this popped up while installing the new LibreOffice, but disappeared before I could read it completely. I hope there is already an answer to this problem. Any help appreciated.
