I have the 32bit version of Libre Office portable 188.8.131.52.
LibreOffice would warn me JRE not installed if I tried to use a feature that required java to run eg when I went File | Send...
So I installed jportable 32bit JRE inside LO's java dir. But now it crashes when I go back to File | Send...
I'm running LibreOffice Portable 3.6.1 on Windows XP.
After a while, I experienced the same message when just opening the File menu, although I had the JRE Portable already installed.
The same problem.
I have Windows 7. I am using Portable LibreOffice 184.108.40.206; I have access to a couple of jave installs:
a) Sun Microsystems Inc. 1.6.0_35 on C:\Program Files\Java\jre6
b) Oracle Corporation 1.7.0_07 on C:\USB8\PortableApps\CommonFiles\Java
With the second version, LO crash. It works with the first (older) java install.
