     All I can suggest are rather generic, as you might expect ..

     - Twist the tails of the application's supplier. If you've licensed
it from a third party, raise merry Hell with their technical support
department. If it's developed in-house, get your boss to drag the
developers back from their newer (cushier?) assignments to fix what they
left behind.  If it was developed in-house and the developers have left
the company, ...

     - Study all the error and status messages you can capture, and try
to understand what might have provoked them.  Perhaps there are ways to
run the installation in a "verbose" mode -- for example, if part of it
is written in Java you might be able to crank up a logging level.  If
parts of the installation procedure are shell scripts (or similar) that
you can modify, try salting them with "Reached point X" messages to help
narrow down the point of failure (if the script got as far as X but died
before reaching Y, focus your attention on what's between).

     - Instead of upgrading, try a "from scratch" installation on a
clean system (probably a test machine).  If things work better you may
not even need to diagnose the problem: Rather, you could say to your
employer "I know a way to get this running, involving the following
steps and taking thus-and-so-much time."

     - Kick the can down the road, and stay with Java 7 for now.  A
significant risk of this approach is that "for now" may slowly morph
into "forever," and since Java 7 is already in its declining years the
eventual reckoning will come sooner rather than later.  But maybe by
that time you'll have moved on, and it'll be your successor's successor
who posts here saying "When I upgrade from Java 7 to Java 10 ..."  ;-)
