The following shows the folder and file organization of the Library Manual materials after installation.
Details of the software are given in the Users' Note (un.html).
Assuming you have downloaded the Library materials from our website, run the self-extracting executable (clw6i26del_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\CL26\clw6i26delor 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 C Library (CLW6I26DEL) in the Start Menu or via All apps from the Start screen (depending on your version of Windows).
The environment variable NAG_CLW6I26DEL is needed by the batch files nagc_example_*.bat (see Section 3.2 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.
The Library Manual may be installed alongside the Library software,
or it may be installed on a different
workstation or server, or viewed from the NAG website
Assuming you have downloaded the Library Manual materials from our website, run the self-extracting executable (setup_cl26_manual.exe) to start the Library Manual installation.
By default, the Library Manual materials are installed in
C:\Program Files\NAG\Mark 26 Manual\nagdoc_cl26or the equivalent for your locale.
The installation will also create shortcuts to the main index files for the manual. The default location of these shortcuts is in the Start Menu or All apps list under NAG Mark 26 Manual. See Section 5 of the Users' Note for details.
clw6i26del_setup.exe /verysilentfrom 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.
Similarly, the /silent or /verysilent switches may also be applied to the Library Manual installer setup_cl26_manual.exe.
In order to enable the software, NAG will issue you with a license key. The license key is contained in a text file consisting of details of the software that will be enabled. For evaluation purposes a trial license may be used. Before obtaining a full license 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 license 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
To request a license 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 CLW6I26DEL Licence,
Request or Install.
Click on the
The NAG support team will send you the Kusari license key by email.
A short term (demonstration or trial) license key contains one or more lines like the following:
CLW6I26DE TRIAL 2016/11/12 "EMnxidA3oeoj0F1Yvi5ibxPjB7"Specifically, it has a line containing the word TRIAL. Longer term license keys must be locked to a specific computer, i.e. they will enable the software on one computer only. These license 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 license 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
The khostid command may be found in the
klreg CLW6I26DE license.datOtherwise the key can be installed for the current user,
klreg /current_user CLW6I26DE license.dat
The environment variable may be set from the Control Panel.
The a00acc example program may be used to check the license is properly installed or the diagnostic program NAG_C_DLL_info.exe can be used to check both accessibility and licensing (see Section 4.2.2).
For each of the DLLs that it loads successfully, NAG_C_DLL_info.exe will print the location of the DLL, and the implementation details as provided by a call to the routine a00aac. It also calls a00acc to check the availability of a valid license key and reports if this is not found; "Status OK" indicates that a valid key was either found or not required.
Note: the diagnostics 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 diagnostics program yourself from the source code provided in the same directory as the executable, using either a Microsoft or Intel C compiler.
