OpenKM community Version Preview not working
That's usually because soffice service has not successfully started during OpenKM startup process.
Can you share stack trace error while trying to preview a document ( complete stack will be shown in logs/catalina.log file ). Share here please.
I suggest you take a look at https://docs.openkm.com/kcenter/view/ok ... eters.html ( check if you have set in your environment ). If you change the system.openoffice.path parameter value you need to restart OpenKM to take effect ( take a look at startup log -> catalina.log file, at the end of the startup tries to run the soffice manager -> if is shown some error then preview will not working )
Finally you can take a look here:
