Replacing Your Existing NQS Installation
========================================

  If your existing installation of NQS is shared by more than one computer
(for example, across a cluster of workstations), then you MUST allow SETUP
to replace your existing NQS installation immediately, otherwise, when
Generic NQS completes a 'staged installation' on the host where the NQS
files are actually stored, Generic NQS will crash/fail to work correctly
on all of the other computers which are using that copy.
