This document covers the following topics:
The person performing the installation must have administrator rights.
During the installation, you are asked to specify an installation directory. Specify the installation directory in which to install your Software AG products.
We recommend that you use the SoftwareAG directory as the location for Natural and its add-on products. But any other directory is also possible.
You can only install Natural on a local hard drive on a Windows system. You cannot install Natural on a network-mounted drive or a SUBST drive.
Important:
It is recommended that you do not install into a directory
which is a subdirectory of a previous installation. Such a previous
installation may have been created either with the Software AG Installer or by
an installation tool that was used in the past.
You can install the same Natural version more than once on the same machine. And you can also install several different versions of Natural on the same machine. This may be necessary to test a new Natural version before it is taken over into a production environment. Each version, however, must be installed in a separate directory. That is, when Natural is already installed, for example, in the directory SoftwareAG, you can install a second instance of Natural, for example, in a directory named SoftwareAG2.
Since Empower only offers the latest version of Natural and other products, it is recommended that you create and keep an image of installed Natural versions for possible later use. Installing from an image rather than downloading it from Empower will usually be faster, too. For further information, see Using the Software AG Installer.
There is one exception: the plug-ins and the terminal emulation which are installed together with the development environment can only be installed once on one machine. Therefore, they are installed into a common Natural directory outside of the above-mentioned installation directory. You can find them in \Program Files\Common Files\Software AG\Natural (32-bit machines) or \Program Files (x86)\Common Files\Software AG\Natural (64-bit machines). When you install a second instance of Natural, the installer checks whether the plug-ins and the terminal emulation in the common Natural directory are older than the ones to be installed. If they are older, they will be replaced with the new version.
While Natural is being installed, it is not possible for another user to install Natural on the same machine. A message with the following information will then be shown: the name of the user who is currently installing Natural, when this installation has been started, and into which directory Natural is currently being installed.
A side-by-side installation of the Natural development environment is only possible if Natural is currently not being used. This is to ensure that the plug-in and terminal emulation files in the common Natural directory can be replaced, if required. A message will be shown with the information that any active Natural sessions need to be closed first. In addition, it is not possible to do a side-by-side installation of Natural if the content of the common Natural directory is currently shown in the Windows Explorer.
When one of the first two digits of the version number changes, we consider an installation as an upgrade installation.
It is not possible to upgrade an existing Natural Version 6.3 or Natural Runtime Version 6.3 with a Natural Version 8.3 installation.
When the first two digits of the version number remain the same and the third or fourth digit changes, we consider an installation as an update installation.
To update Natural, specify the same directory and select the same items to install.
An update installation does not prompt again for license files, configuration data, and port numbers. The existing license files, configuration data, and port numbers will be used.
By default, a new FNAT is created in the installation
directory during the installation of Natural
(<install-dir>/Natural/fnat).
This FNAT must always exist, and the global configuration file
must have an entry which defines this FNAT.
The Natural add-ons (such as Predict or Natural Business Services)
can only be installed into this FNAT.
Note:
If you want to check or edit the settings in the global
configuration file, use the Configuration Utility.
The Software AG Installer maintains an internal list of installed
products, which must coincide with the add-ons that are currently installed in
the FNAT. This is important for updates and uninstallations to
work correctly.
For this reason:
Do not install products into the FNAT without the
use of the Software AG Installer.
Do not replace the default FNAT
(<install-dir>/Natural/fnat)
with another FNAT.
Make sure to complete the installation of an add-on by using the SYSPCI utility.
If an error occurs due to the above-mentioned scenarios, the only way to solve the problem is a new installation. In some situations, one of the following workarounds may help:
Workaround 1: Complete the previous installation by using the SYSPCI utility.
Workaround 2: Uninstall the product and then start the installation once more.
By default, a new FUSER is created in the installation
directory during the installation. If you want to use an existing
FUSER of Natural Version 6.3, you have to adjust the system file
settings in the global configuration file after the installation. See also
Overview of Configuration
File Parameters in the Configuration
Utility documentation.
You can install both Natural and Natural Security at the same time, or you can install Natural Security after having installed Natural.
To become operable, Natural Security requires a post-installation configuration and initialization step. This includes:
setting or loading the Natural Security log file,
setting or loading the Natural Security file
FSEC,
adjusting the Natural parameter files,
adjusting the global configuration file.
See also Setting Up Your Products Using the SYSPCI Utility in the section Completing the Installation. This step is not necessary after an update installation.
The following restrictions apply if you install Natural Security together with Natural Runtime:
It is only possible to use an existing Natural Security
FSEC file.
Once you have installed Natural Security, it is not possible
to access the SYSSEC application, even if you are a Natural
Security administrator.
Important:
Once you have installed and configured Natural Security,
Natural on the assigned system file (FNAT) can only be accessed
under the control of Natural Security. Natural Security cannot be removed once
it has been installed. It can only be removed if you uninstall the whole
Natural environment in which Natural Security has been installed.
