## Administrator Status

The person performing the installation must have administrator status.

## Installation Directory

During the installation, you are asked to specify an installation directory. Specify the installation directory in which to install Entire System Server (NPR). In case you want to use Entire System Server (NPR) together with Natural or other Software GmbH products, specify the installation directory in which you have installed these products. The user that you are using to install must have full read and write permissions to this directory.

We recommend that you use the C:\Program Files\Common Files\softwareag directory as the location for Entire System Server. But any other directory is also possible.

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.

The npr.ini file is delivered with Entire System Server (NPR) in the <install-dir>\EntireSystemServer directory. To be able to share a global npr.ini configuration file by multiple Entire System Server (NPR) installations, the installation copies the npr.ini file to the C:\Program Files\Common Files\softwareag\EntireSystemServer directory. The <install-dir>\EntireSystemServer directory will not be removed by an uninstallation.

Entire System Server (NPR) searches for the npr.ini file

1. at the place where the environment variable `NPR_INI` points to

2. in the C:\Program Files\Common Files\softwareag\EntireSystemServer directory

3. in the <install-dir>\EntireSystemServer directory

If a user wants to use the local npr.ini file in the the <install-dir>\EntireSystemServerdirectory, he has to make sure that `NPR_INI`does not point to an npr.ini file and he must delete or rename the npr.ini in the C:\Program Files\Common Files\softwareag directory.

During the installation, the script <install-dir>\EntireSystemServer\INSTALL\inatnpr.bsh is executed. If Natural is already installed in the installation directory, the script copies shared libraries of Entire System Server (NPR) into the NATEXTLIB directory.

## Side-by-Side Installations

You can install the same Entire System Server (NPR) version more than once on the same machine. And you can also install several different versions of Entire System Server on the same machine. This may be necessary to test a new Entire Systen Server version before it is taken over into a production environment. Each version, however, must be installed in a separate directory. That is, when Entire System Server is already installed, for example, in the directory C:\Program Files\Common Files\softwareag, you can install a second instance of Natural, for example, in a directory named C:\Program Files\Common Files\softwareag2.

If you install Entire System Server (NPR) more than once in different directories, these Entire System Server installations may share one npr.ini file.

Since Empower only offers the latest version of Entire System Server and other products, it is recommended that you create and keep an image of installed Entire System Server 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.

## Upgrading Your Entire System Server (NPR) Environment

When one of the first two digits of the version number changes, we consider an installation as an upgrade installation.

## Updating Your Entire System Server (NPR) Environment

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.

It is not possible to update an existing Entire System Server Version 2.1. SP4 with an Entire System Server Version 2.1. SP8.
