Where is LO looking for a JRE?

LO can’t find my recently installed JRE (Java version 8.171 build 1.8.0_171B121) located in c:\windows\program files (x86)\java\jre1.8.0_171. Should I rename my JRE folder, and if so, to what?

Please edit your question to include the exact text (version information) from Help->About. Application bitness is important.

Also, what is exact message when LO doesn’t find JRE?

You installed a 32 bits version of Java and you apparently have a 64 bits LibreOffice. That won’t work, both have to be either 32 or 64 bits.

“Bitness” was the problem. My LO is 64-bit but the JRE was in the 32-bit program folder. I got the 64-bit JRE installed and Base now works. Thanks for the solution!
