4 Installation

4.1 Library Software and Manual Installation

4.1.1 Library Installation

Assuming you have downloaded the Library materials from our website, run the self-extracting executable (nlw32272el_setup.exe) to start the Library installation. The Library Manual materials are available as a separate download.
By default, the Library materials are installed in
  C:\Program Files\NAG\NL27\nlw32272el
or (if a 32-bit Library is installed on a 64-bit machine)
  C:\Program Files (x86)\NAG\NL27\nlw32272el
or the equivalent for your locale.
The installation procedure will also create several shortcuts, which are described in this document or in the Users' Note. The default location of these shortcuts is under NAG Library (NLW32272EL) in the Start Menu or via All apps from the Start screen (depending on your version of Windows).
The environment variable NAG_NLW32272EL is needed by the batch files nag_example_*.bat (see Section 3.3 of the Users' Note). This is set in the registry as part of the installation procedure. Optionally, the PATH, LIB and INCLUDE environment variables may also be updated during installation.
This software is provided with an uninstallation facility via the Windows Control Panel.

4.1.2 Library Manual Installation

The Library Manual may be installed alongside the Library software, or it may be installed on a different workstation or server. Alternatively, the Library Manual may be viewed from the NAG website (https://www.nag.com/numeric/nl/nagdoc_27.2/).
Assuming you have downloaded the Library Manual materials from our website, run the self-extracting executable (setup_mk27-2_manual.exe) to start the Library Manual installation.
By default, the Library Manual materials are installed in
  C:\Program Files\NAG\Mark 27-2 Manual\nagdoc_27.2
or the equivalent for your locale.
The installation will also create a shortcut to the main index file for the manual. The default location of this shortcut is in the Start Menu or All apps list under NAG Mark 27-2 Manual. See Section 5 of the Users' Note for details.

4.1.3 Silent Installation

This product may be installed in silent (unattended) mode by running
  nlw32272el_setup.exe /silent
or
  nlw32272el_setup.exe /verysilent
from a Command Prompt. With the first version, the user sees a progress bar on the screen as the installation occurs, whereas with the second, nothing is displayed. The files will be installed to the default location and the PATH, LIB and INCLUDE environment variables will be modified. The default installation location may be overridden by using the /dir switch, e.g. /dir="C:\my folder". To prevent the environment variables being updated, the /type=noenv option may be used.
Similarly, the /silent or /verysilent switches may also be applied to the Library Manual installer setup_mk27-2_manual.exe.

4.1.4 Licence Management

The use of this product is controlled by the Kusari licence management system. This release of the Library uses version 2.2-88 of Kusari.
In order to enable the software, NAG will issue you with a licence key as follows. The licence key is contained in a text file consisting of details of the software that will be enabled. For evaluation purposes a trial licence may be used. Before obtaining a full licence you need to know the Kusari hostid of the system on which you intend to use this product. How to do this is described below.
The easiest way to request a licence key is to use the Kusari Installer GUI described in the next section. Once you have a key, the same GUI can be used to install it.
The information below covers the most common requirements. For more complex licensing situations, please see the Kusari documentation (the files k-using-win.pdf and k-install-win.pdf in the nlw32272el\license\doc folder). See also the Kusari Frequently Asked Questions.

4.1.4.1 The Kusari Installer licence key request and key installation program

The recommended way to request a licence key is to use the Kusari Installer GUI program provided. This will help you to build a standard message requesting either a trial key or a full key which can be pasted into an email to the NAG Technical Support Service. This message will include the Kusari hostid.
To request a licence key, run the Kusari Installer program, which may be accessed at the end of the installation procedure or via the Start Menu or All apps shortcut NAG NLW32272EL Licence, Request or Install. Click on the Request New Licence button to bring up the New Licence Request form. Fill in your details and click on Generate Licence Request, then paste the generated information into your email client and send it to the NAG address given at the top of the generated information.
The NAG support team will send you the Kusari licence key by email.
A short term (demonstration or trial) licence key contains one or more lines like the following:
<PRODUCT_CODE> TRIAL <EXPIRY_DATE> "EMnxidA3oeoj0F1Yvi5ibxPjB7"
Specifically, it has a line containing the word TRIAL. Longer term licence keys must be locked to a specific computer, i.e. they will enable the software on one computer only. These licence keys typically include the word NODE or FULL instead of the word TRIAL above and may contain extra fields.
Once you have obtained one of the above licence keys, the Kusari Installer program may be used to install the key in the Windows Registry. Paste the key into the edit box on the main Kusari Installer dialog and then click on the Install Licence Key button to install it.

4.1.4.2 Command line licence key request

If for any reason it is impractical to use the GUI, the command line program khostid may be run instead. The output of this command should be sent to the NAG Technical Support Service with your details, your organisation details and your NAG customer reference number (if known).
The khostid command may be found in the nlw32272el\bin folder.

4.1.4.3 Command line installation of the licence key in the registry

If not using the GUI, the klreg program may be executed from a Command Prompt to install a key in the registry. This program may be found in the nlw32272el\bin folder. First put the licence key in a file, say licence.dat. If you have administrator privileges you can install the key for all users,
  klreg NLW32272E licence.dat
Otherwise the key can be installed for the current user,
  klreg /current_user NLW32272E licence.dat

4.1.4.4 Installing the licence key in a file

You are recommended to install the licence key in the registry as described above. If this is not suitable an alternative method is to put the licence key into a file accessible from the machine for which the software is licensed and set the environment variable NAG_KUSARI_FILE to the full pathname of the licence file.
The environment variable may be set from the Control Panel.

4.1.4.5 USB key licences

Simply insert the USB key in any spare USB socket on the machine on which you wish to run this product.

4.1.4.6 Testing the licence

The a00acc or a00acf example program may be used to check the licence is properly installed or the diagnostic program NAG_Library_DLL_info.exe can be used to check both accessibility and licensing (see Section 4.2.2).

4.2 Further Information

4.2.1 Checking the Installation

Access to the Library materials can be checked by running a few example programs following the advice given in Section 3.1 of the Users' Note; a suitable sample would be d01rkf, e04uca, f07adf, d01rjc, f07adc and g05sjc. The installation can also be tested using the batch files nag_example_*.bat (see Section 3.3 of the Users' Note).

4.2.2 Accessibility Check

The diagnostic program NAG_Library_DLL_info.exe, which by default is located in C:\Program Files\NAG\NL27\nlw32272el\diagnostics, may be used to check whether the DLLs NLW32272E_nag.dll and NLW32272E_mkl.dll are accessible from the current environment. If this program is started from Windows Explorer or from the Check NAG NLW32272EL DLL Accessibility shortcut via the Start Menu or All apps, the DLLs will be found if the global PATH environment variable has been set to include their location. If it is run from a Command Prompt window, then the environment local to that window will prevail. (See Section 3.1.1 of the Users' Note for more information on environment variables.)
For each of the DLLs that it loads successfully, NAG_Library_DLL_info.exe will print the location of the DLL, and the implementation details as provided by calls to the routines a00aac and a00aaf. It also calls a00acc to check the availability of a valid licence key and reports if this is not found; "Status OK" indicates that a valid key was either found or not required.
Note: the diagnostic program executable may not be compatible with all versions of Microsoft Windows (in particular, Microsoft Windows XP), and you may get a "not a valid application" error when you try to run it. In that case, you may simply recompile the diagnostic program yourself from the source code provided in the same directory as the executable, using either a Microsoft or an Intel C compiler.
