Section 2. Installation, Operation and Backup Procedures
Note that the trial version will install some applications in the C:\Program
Files\Campbellsci\Demo directory. When the purchased version of LoggerNet
is installed, these applications will each be installed in their own directory
under C:\Program Files\Campbellsci. The versions in the Demo directory will
no longer be used. Therefore, to avoid having these unused versions remain on
your computer, you may wish to uninstall the trial version before installing the
purchased version of LoggerNet.
2.2 Upgrade Notes
If you have any version of LoggerNet 3 installed on your computer, when you
run the installation the existing version will be updated with the new files. If
you have any version of LoggerNet 2 installed, you can choose to upgrade that
installation, or install LoggerNet 4.x separately while leaving the previous
version intact.
When you upgrade an existing installation, LoggerNet will continue to use the
network map, data collection schedules, data file locations, etc., of the existing
installation. Essentially, you will be able to “pick up where you left off” the
last time you used LoggerNet.
LoggerNet 4.x can readily use the network map from LoggerNet 2.x or 3.x.
However, network maps are not backwards compatible. If you upgrade your
existing version, once LoggerNet 4.x is opened, the network map will no
longer be compatible with LoggerNet 2.x or 3.x. For this reason the upgrade
installation will automatically make a copy of the
<WorkingDirectory>\LoggerNet\sys directory and all of its contents. The copy
will reside in <WorkingDirectory>\LoggerNet\
NetworkMapBackup\<version>\sys. If it then becomes necessary to revert
back to a previous version of LoggerNet, you will need to remove the
<WorkingDirectory>\LoggerNet\sys directory and replace it with the
<WorkingDirectory>\LoggerNet\NetworkMapBackup\<version>\sys directory.
If it does become necessary to revert back to an older version of LoggerNet,
you must first uninstall LoggerNet 4.x and follow all prompts given while
uninstalling, including rebooting your computer. You can then install the
previous version of LoggerNet. Note that you cannot expect a backup made in
LoggerNet 4.x to restore properly in an older version of LoggerNet. Also, as
noted above, network maps are not backwards compatible. Trying to use a 4.x
network map in an older version of LoggerNet may corrupt the network map
such that it can no longer be used in LoggerNet 4.x.
2.3 LoggerNet Operations and Backup Procedures
This section describes some of the concepts and procedures recommended for
routine operation and security of the LoggerNet software. If software and
computer systems were perfect this section would not be necessary. However,
since this software is required to run with predictable results in the real world
on real computers, the following guidelines and procedures will be helpful in
minimizing possible problems that may occur.
