Re: Octave 4 installer doesn't detect JRE at install time

[John Frain]

The  JavaHome settings in the registry on my windows 8.1 PC are in
SOFTWARE\JavaSoft\Java Runtime Environment\1.8 and in
SOFTWARE\JavaSoft\Java Runtime Environment\1.8.0_20.

SOFTWARE\JavaSoft\Java Runtime Environment\CurrentVersion is 1.8

The Octave installer does not find the run-time environment as set out
in my earlier email
