Ah, now we're cooking! I am afraid you need to implement a solution for
every platform your software could be used on. On *nix you could
evaluate the output of "mount" to find out, on Windows you probably need
to look at "net use" etc. Maybe on POSIX OS there is a system call that
will help so you could write a JNI extension.
This method certainly helps:

If you want to prevent multiple instances running concurrently from one
installation you could use a file in the installation location.
However, proper file locking in a platform independent way is another
tricky task in Java.
Btw, I don't see how the installation location actually makes a
difference. You could still install the program on each system and run
it multiple times. Why do you need to prevent running from a network drive?
Kind regards
