64 Bit Jre For Libreoffice

Posted onby admin

Now OpenOffice works with JRE 32-bit, shall I just remove the 64-bit one, or leave that on also? The different bit-versions of the JRE can work on same PC in same time.

In LO it is Tools Options LibreOffice Advanced. LO 6.4.4.2, Windows 10 Home 64 bit See the Writer Guide, the Writer FAQ, the Writer Tutorials and Writer for students. As far as I know, the 32 bit Java and the 64 bit Java are installed in different locations on 64 bit Windows. Apache OpenOffice 4.1.9 on Xubuntu 20.04.2 (mostly 64 bit version) and very infrequently on Win2K/XP.

Whenever I try to launch LibreOffice it says I need to download a JRE and then restart LibreOffice? How do I do this? I have all come into trouble with Language Tool Extension with LibreOffice. Whenever I try to get it enabled it says the Java Implementation Loader failed. And when I go to the Advanced setting tab no JRE appears in the box below. So I am wondering how to install a JRE and if that will fix both issues? I am running Windows 64 bit and Java 32 bit.

I am running Windows 64 bit and Java 32 bit.

And that might be the problem. If you run a 64-bit LibreOffice (which you did not mention - please provide information from Help -> About LibreOffice menu) then you need a 64-bit JRE for LibreOffice to recognize the JRE installation - see also FAQ

This worked thank you!

Java Access Bridge set-up archival details (applicable for LibreOffice < 4.2.0 and earlier)

Upcoming builds of LibreOffice (> 4.2.0.0 dev, > 4.1.0.4, > 4.0.5.0 dev) have implemented support for Oracle Java SE 7, Java Runtime Environment (JRE) 1.7u45 with its imbedded Java Access Bridge (JAB) v2.0.3 (activated with a 'jabswitch -enable' command). Or users preferring so may continue to use Java SE 6, and JRE 1.6u45, with an installation of JAB 2.0.2. -- 2013-07-24

LibreOffice release builds prior to 4.0.5 (i.e. 3.5.7, 3.6.7, 4.0.4) do not support Java SE 7 Java Accessibility API roles exposed to the JRE, and those versions still require use with a JRE 1.6 version and a JAB 2.0.2 installation.

LibreOffice 3.6.4 build restored AT tools support for Java Accessibility roles using JRE and JAB mappings of the UNO Accessibility API roles. Builds 3.6.0, 3.6.1, and 3.6.3 did not provide AT tools support. LibreOffice 3.5 builds through 3.5.7, 3.6.4 - 3.6.7, and now the 4.0.4 builds provide functional AT with a correctly configured Java 6 Runtime Environment and the Java Access Bridge, v2.0.2.}}

Oracle 'Java Accessibility Bridge' and JRE configuration

Install (clean & reinstall) in this order:

  1. Java Runtime Environment (1.6u45, or 1.7u45)
  2. Java Access Bridge (install 2.0.2, or enable 2.0.3)
  3. LibreOffice ( 3.5.7 < or > 3.6.4 including > 4.1.0 )

Folks should understand that for the Windows OS builds, the Java Accessibility Bridge (JAB) foundation for LibreOffice Assistive Technology and Accessibility Tools is one of the primary components entirely dependent on a functional system wide JRE (a full list of Java dependencies is here).

Additionally for the Windows OSes, Java Access Bridge, LibreOffice AT, and Java components of LibreOffice on Windows require use of a 32-bit JRE to function. Calls to a 64-bit JRE will fail.

For Windows users either JRE 1.6u45 or JRE 1.7u45, Oracle's latest release of the respective branches, are completely functional with LibreOffice when properly configured.Note: JRE 1.7 builds > 6 now install Java Access Bridge version 2.0.3 by default, but it is disabled and must be enabled for use--with a 'jabswitch -enable' command. Full instructions from Oracle here.

  • Both JRE will support Oracle's Java Accessibility Bridge and Assistive Technology and the Accessibility Tools in LibreOffice.
  • Both JRE have the latest Oracle security patches to allow the included browser plug-ins to be used safely.

Problems for LibreOffice use on Windows will occur when the JRE is not configured correctly. For LibreOffice users that have had a JRE 1.6 installation and have problems following a JRE 1.7 installation. Doing an 'upgrade' installation to JRE 1.7 does not clear the JRE 1.6 per-user configuration that LibreOffice had been using. You must manually delete the javasettings_Windows_x86.xml file in each per-user C:Users<userName>AppDataRoamingLibreOffice4userconfig folder.

Unfortunately, users of 64-bit Windows are also tripped up by the Oracle JRE installers (or Ninite installer packaging) and receive installations of both 32-bit and 64-bit JREs.

These Windows JRE installers finish an installation by copying program executables into the C:WindowsSystem32 and C:WindowsSysWOW64 folders.This causes problems for LibreOffice Java Access Bridge dependent users. Simply put, the wrong version of the JRE gets called.


There are two methods to correct the problem for a 64-bit Windows user:

  • install only a 32-bit JRE. Perform a manual 'offline' installtion of just the 32-bit JRE. Found here for JRE 1.7u45 downloads. or here for JRE 1.6u45 downloads.
  • force use of a 32-bit JRE by removal of the copied executables from the Windows system folders, and making an entry to find the 32-bit JRE installation location on system PATH variable.
Convention says use a JAVA_HOME variable, but appending the full path to the JRE bin directory is just as effective, e.g. append ';C:Program Files (x86)Javajre7bin' to the PATH variable.

Sounds simplistic, but if you start with a correctly configured 32-bit JRE install, the JAB will install cleanly--for JRE 1.6u45 enable the built-in JAB v2.0.3, now bundled and installed by default with JRE > 1.7.u6--but not enabled, as referenced by Oracle here.

Activating LibreOffice Assistive Technologies on Windows OSesThere are 3 options to activate

64 bit jre for libreoffice windows 7
  • If installing LibreOffice 3.5.7, activate Assistive Technology by launching LibreOffice and navigating to the ToolsOptionsAdvanced/Java options menus, and then also to the ToolsOptionsAccessibility menu to make selections.
or
  • If installing the 3.6 release, LibreOffice 3.6.4 or newer, there is now a checkbox option on the installation panel to 'Support assistive technology tools' during the installation--for ALL users on the Windows system. This checkbox will enable JRE support in LibreOffice while enabling assistive technologies. Note: when using this installation option, your must first have enabled the Java Access Bridge as above prior to the installation. And at completion of the installation you must logoff and then logon for the Windows user profile to be refreshed and support for accessibility features to be activated.

or
  • Finally, for any LibreOffice build, if just a single user requires activation of Assistive Technologies, the following text can be saved as a registry configuration batch file--.REG-- extension and run by each individual.
