No suitable Java VM found / XUbuntu 14.04/32bit

One of the ward members who I moved to Linux a few years ago saw a prompt on her computer to upgrade it from XUbuntu 12.04 to 14.04, so she clicked it, and then walked away, and forgot about it. Along comes hubby and noticing the laptop was still turned on but with a screen blanker, turned it off.. When the good sister tried to start her machine, it spouted a bunch of errors and thats when she called me. I decided to backup her /home directory and do a clean install of XUbuntu. At the moment, I've completed *everything* but her install of the Indexing program. Having not had to install it for quite a while, I somewhat expected it to install without any problems on a 32bit Linux. Apparently I was mistaken.. Each attempt to install the Indexing app gives me the following error:
The one part of that error makes me curious, assuming its not
a error itself is WHY is such an ancient Java version still being used?
I'm a retired sysadmin/support tech, and I retired in 2010, and 1.6
was considered old at *that* time.. The system has a valid 1.7 version
on it. I tried pointing INSTALL4J to all of the above with zero success..

Just for fun, I went to the Oracle Java 1.6 website and they state
WARNING: These older versions of the JRE and JDK are provided to help
developers debug issues in older systems. They are not updated with the
latest security patches and are not recommended for use in production.

Help!

This patch has worked perfectly for me and my Ubuntu 14.04 netbooks. It was designed by someone for whom I am so grateful.
I created a file that I called fs.sh and run it: sudo bash fs.sh and then I simply wait it does everything I need to make it work.

Reluctantly, I went ahead and installed Java 1.6 and it worked... I guess if the devs are all busy working on the web-based Indexing project, nobody has the time/inclination to update the current Indexer to a bit more moden JRE..
