The LibreOffice configuration has been changed. Select the Java runtime environment

Today, after launching LO writer, I get this screen:

I can go ahead and select the JDK path, but I wonder what could have caused this to happen? Haven’t changed any JDK, haven’t reinstalled, removed or anything alike. Basically, I’ve touched neither Java, nor LO, nor OS update. It’s just started out of the blue. Can I find out what could be the reason? Also, how would I know which Java version fits my LO version?

Thanks.

It was Update Tuesday for Windows yesterday/today

Could you please elaborate a bit? What was “Update Tuesday”? Did something updated remotely (on LO servers or wherever) and that caused any changes in my local installation? Didn’t get it.

Every second Tuesday of the month, Microsoft releases updates for Windows. These get automatically downloaded and installed but until the computer is rebooted the operating system (and hence programs relying on it) can be in an uncertain state. Close everything and click Start menu > Power > Restart (Not Power off), you might need to do it a second time if it downloads more updates after restart.

Ah… you’re talking about standard Windows updates. I’ve not restarted, nor updated anything these days… especially, I’ve not changed anything with Java/JDK. Just only one security patch update was waiting for the restart, and now I have done that restart, as well. Completed update. But it’s still the same window showing up. I don’t think that security patch have caused JDK replacement/removal.

JDK or JRE?

How to install Java (JRE/JDK) so that LibreOffice could use it?

As you are on Windows then LibreOffice might be updating automatically. Click Tools > Options > LibreOffice > Online Update and untick Enable automatic update to disable.
