I have Zotero stand alone version 5 and Libre Office Version: 5.4.1.2 (x64) running on Windows 10
The LibreOffice plugin stopped working at the last update and I have removed it from LibreOffice and then tried re-installing it again. Tried to install from Zotero download and then from within LibreOffice but by both ways I got this error message:
"Could not create Java implementation loader"
Progress report.
- Checked LibreOffice Java Options = no JRE showing
- Downloaded same from Java site = http://www.oracle.com/technetwork/java/javase/downloads/jre9-downloads-3848532.html#close but during unpacking there was an error!
- Downloaded complete file from Java site and installed without need for unpacking.
- Shut down LibreOffice
- Restarted and checked to see if JRE appeared on list. It does not. Tried to find folder but LibreOffice did not like any folder that I found.
6 Uninstalled everything and tried re-installing it all, latest versions. Does not work.
Second Try:
Right success.
- Uninstalled everything
- Installed Java JRE_1.8.0_144
- Installed LibreOffice 5.3.6.1 x64 (latest stable conservative user)
- JRE appears in Java Option list
- Zotero plugin works
- Able to add endnote references to documents using plug in and standalone Zotero
So looks as if JRE-9 does not work with Zotero plug in for LibreOffice
