JREs which are installed into C:\Program Files (x86) (as opposed to C:\Program Files) are 32-bit (unless you manually modified install path during installation), so you may use this information to tell if your JRE is 32-bit or 64-bit. How to control what JRE version in installed This is why you have to use the manual download link. Thus, be aware that 'standard' build, with a naming scheme like JavaSetup8u341.exe will NOT work with LibreOffice.


LibreOffice can only use JRE with matching architecture: i.e., 64-bit LibreOffice can only use 64-bit JRE, and 32-bit LibreOffice can only use 32-bit JRE.

You may check the architecture of installed LibreOffice in menu Help ▸ About LibreOffice, where the version string looks like "Version: 6.4.5.2 ( 圆4)" for 64-bit version, and "Version: 6.4.5.2 ( x86)" for 32-bit version. If you have 32-bit operating system, you will be offered a 32-bit installer ( Windows (32-bit) ).If your Windows is 64-bit, LibreOffice Download page by default offers you a 64-bit LibreOffice installer.

To use them, a supported version of JRE/JDK must be present and configured on the system.ĭo not mistake '圆4' and 'x86' architectures: when using Windows, you need to make sure that the architecture of installed LibreOffice matches the architecture of installed JRE. Some LibreOffice functions require Java ( JRE/ JDK).
