I am unable to install many extensions due to the error 'Could not create Java Implementation Loader'. I have rechecked the java path etc and not having any luck. I tried un-checking the 'use java runtime' and that did not help. I would also like to know how to remove extensions that came bundled-I do not nee all the language extensions that are installed. Perhaps that is not possible. USing LibreOffice 3.5.6.2 on Vista. Is it because I have Java tm 7 update 5 and JavaFX 2.1.1 installed? Thanks in advance.

LibO support Java 7, but (especially on 64-bit Windows) you might receive warnings about the Java version being defective. In that case, download and install the most current JRE 6 version http://www.java.com/java6download/ . Make sure you get the file "Windows x86 Offline (32-bit)". Then configure LibO to use it at "Tools - Options - LibreOffice - Java"

A bit late maybe, but I suffered from the same. I could resolve it by selecting "Tools - Options... - LibreOffice - Advanced" and then selecting one of the possible JRE's that were installed on my computer (none were selected by default). I'm using LO 4.2.2.1.

To avoid confusion, the exact error message is "Could Not Create Java Implementation Loader" ("loader", not "folder").

We now have a source-level analysis here.

The most successful workarounds are described here it seems.

Well, I uninstalled the existing java, then installed java6. So far so good. This seems to have done the trick. Time will tell. Thank you for your help!

I seem to be having the same problem on Linux (Mint 14; Kernel 3.5.0-17) running LibreOffice 3.6.2.2.

Looking at the package manager I seem to have mostly JRE6 components installed despite the package billing itself as a JRE7 package: icedtea-plugin (removed), gcj-jre (installed), icedtea-6-jre-cacao (installed), libgcj13 (installed), gcj-4.7-jre (installed), gcj-jre-headless (installed), gcj-4.7-jre-lib (installed), libgcj-common (installed), openjdk-6-jre-headless (installed), openjdk-6-jre (installed), icedtea-6-jre-jamvm (installed), openjdk-6-jre-lib (installed), gcj-4.7-jre-headless (installed), icedtea-7-plugin (removed), libgcj13-awt (installed), default-jre-headless (installed), openjdk-7-jre (removed), gcj-4.7-base (installed).

Any thoughts?

Thank you Timon. I will give it a try and report back. I filed a report at Java on why I did not want the latest version.

Just wanted to add I heard back from java after filing a report. They said it is a Libre Office bug and pointed me to this thread. https://bugs.freedesktop.org/show_bug.cgi?id=50371

1) exit LibreOffice and quickstart.exe

2) run cmd.exe (Prompt)

3) In Prompt, delete file "%appdata%\LibreOffice\4\user\user\extensions\buildid"

4) In Prompt, set environment java_home

set java_home=C:\Program files (x86)\Java\jre1.8.0_65 (LibreOffice 32 bits) set java_home=C:\Program files\Java\jre1.8.0_65 (LibreOffice 64 bits)

notice: path your java

5) In Prompt, run "path\LibreOffice\program\soffice.exe"

6) exit cmd.exe

Run fine in windows xp sp3 32 bits, jre 1.8.0_65 and LibreOffice 5.0.3.1

I solved the problem system Windows 7 Ultimate SP1 64 bit:

  1. In Control Panel, revealed hidden folders.
  2. Closed LibreOffice and deleted the users\your folder\aptdat\roaming\LibreOffice folder.
  3. Installed the latest 32 Bit Java.
  4. Opened LibreOffice, left click on Tools-Options-Advanced, you should see in the windows 2 versions of the latest 1.8.0_51 Java, select the 32 Bit version as LibreOffice is installed into Program Files (x86) folder.
  5. Note it shows you that Java.exe is located in Program Files\Java no it isn't! It's there but in Program Files\Java\jre1.8.0_51\
  6. Left click on Parameters and type C:\Program Files (x86)\Java\jre1.8.0_51\java.exe and click Add.
  7. Close and Reopen LibreOffice, now you will be able to add Extensions.

I had a problem with the path variable and learned that in C:\Program Data\Oracle\Java\Javapath\ are three SYMLINK pointing to java.exe, javaw.exe and javaws.exe

What's important is that this SYMLINK are created by every java actualization. Therefore is preferable to point to that place. Any way, the path variable will send LO to that place if looking for java.
