This is almost certainly not a new problem, but I haven’t been able to find a solution. My basic problem is that I don’t have a clue what JRE actually does, or why Libre Office needs it at all, so I would welcome any advice suitable for the ‘fairly intelligent but totally ignorant’ user!
I have built a quite simple Libre Office database (names, addresses, tel nos etc) on my desktop, under Windows 10. I have used a USB stick to transfer it to my laptop, also running Windows 10. It fails to run, telling me I have an out-of-date version of JRE.
I have of course made sure I have the most current version of Java on my laptop, but it makes no difference. Perhaps it is installed in the ‘wrong’ folder, ie not where Libre Office is looking for it? Or perhaps there is some other explanation.
