As I understand it, there can be any number of installed JREs and JDKs on a
Windows machine, but only one will have the
HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\Java Runtime Environment registry item
set.

So I think the above registry can be used to detected an installed JRE
(including the version). The "CurrentVersion" value should store the
version number string.
