Languagetool crashes repeatedly Libreoffice installation

How can I remove completely the extension language tool? It crashes the startup of Libreoffice after installation. I have multiple times de-installed LibreOffice, carefully removed any languagetool files in my Windows system, looked in the Windows registry to any references of Languagetool. This happened after I tried to add the LanguageTool addition, which generated a Java error. But still, after every new installation of LibreOffice it says it is enabling language tools at first opening, and crashes. Libreoffice 3.5.4

I did reinstall it with deselection of language tools, no solution. I also removed any trace of a java 7.4, which might cause problems.

With newest version of LibreOffice (3.6.3) and the latest Java update, I could get rid of that problem.
Now Language Tool works fine!

To answer my own question, deleting version 3.5.4 and Java, then reinstalling 3.4.6 and Java 7.4 solved the problem. Opening 3.4.6 generated several Java error messages, but only once. Then upgraded again to 3.5.4, now opens correctly.

Did not try to reinstall the ‘LanguageTool’ extension.
