Hi,
I have no idea how/why Java finds libraries not located in one of the
paths indicated by the program.
I only sporadically use Windows, and I used this program to debug the
installations on various systems (Windows, Linux, Mac OS X) with
success. I think, the last time I had to use it was on a Windows system
and, if I remember correctly, it showed also the JRE/bin directory.
Since the owner of that system is sick, I cannot currently verify this.
If the installation works even though the lib directory you are using is
not shown, then I guess there is nothing to worry about :-). If it does
not run, one should be able to get it to run by moving the libraries
into one of the directories indicted by this program. The program also
helps to debug other problems, as with the more detailed error message
you can see whether the JVM could not find the library, or could not
load it (e.g. missing access rights, wrong binary format/platform).
Cheers,
Urs
