Nullsoft Installer: Simple installer with JRE check

Hi,

  I just stumbled over the NSIS (Nullsoft Scriptable
Install System) site at sourceforge and browsed its
real-world installer script archive.

  One real-world script entry, for example, is titled
"Simple installer with JRE check" and weebib
introduces the script as follows:

  This is a not very fancy install that has one
interesting feature though. It can achieve a JRE
version check. Depending on the outcome of the check
procedure, it will display a Window warning the user
that a newer version will be installed. (it is still
time to cancel)

  As it has been pointed out in the forum, there ought
to be another solution to perform a much more thorough
search for the JRE than the one achieved by the
present installer. In time, the use of a dll might be
necessary to scan the hard drive as the final
solution.

  The big effort of this install was to use an
(optional) InstFile window while installing the jre.
