=====================================

-----------------------------------------------------------------------

=======================================================================

     1. Prerequisites
     2. Installation
        2.1 Apply a license

=======================================================================

1. Prerequisites
================
Altair SLC and Altair Analytics Workbench are supported on either
Windows 10 and later running on x86_64 hardware, or Windows Server 2016
and later running on x86_64 hardware.

There are no other prerequisites.

You will need to have administrative access to install Altair SLC.


2. Installation
===============
Before starting to install Altair SLC or Altair Analytics Workbench,
ensure that your copy of Windows has the latest updates and service
packs applied.

Altair SLC and Altair Analytics Workbench are provided as separate
installation programs which are available from the Altair One
marketplace at www.altairone.com. You will require a username and
password to access the download section of the site.
The installation programs are:
- altairanalyticsworkbench-<version>-windows-x86_64.msi
- altairslc-<version>-windows-x86_64.msi

Where <version> is the release version of the installation program.
Ensure that you have the same release version for both
installation program.

Use of the Altair SLC engine is controlled by means of a license which
must be applied after installation. If only Altair Analytics Workbench
is installed on a workstation, that workstation will not require
a license.

- To use Altair Analytics Workbench only, for example to connect to a
  remote installation of the Altair SLC engine, you require the
  altairanalyticsworkbench-<version>-windows-x86_64.msi
  installation program.

- To use Altair Analytics Workbench and the Altair SLC engine on the
  same device, you require both installation programs.

- To use the Altair SLC engine only, for example on a Windows Server,
  you require the altairslc-<version>-windows-x86_64.msi
  installation program.

Once the required installation (.msi) program is downloaded,
double-click the files, read and accept the EULA and follow the
on-screen instructions. Each installation program must be run
independently.


2.1 Apply a license
===================
A license is required to run Altair SLC, this can be either
Altair Units or a wpskey license file. Altair Units are served from
either a hosted by Altair (HHWU) or an on-site the
Altair License Manager (ALM); a wpskey license file is downloaded from
the World Programming website (https://www.worldprogramming.com).

If a workstation has both Altair SLC and Altair Analytics Workbench
installed, the license can be applied through Workbench. For more
information see the Altair Analytics Workbench User Guide in your
installation, or available from the Altair community documentation
site (https://help.altair.com).

Where only Altair SLC is installed:

- If using the Altair hosted license server, you need to specify the
  ALM_HHWU environment variable and obtain a configuration file to link
  the server hosting Altair SLC with the Altair hosted license server.
-	Log in to your Altair One account. In your user profile page, obtain
  an Altair One authorization code for the server hosting Altair SLC.
  Note that this code has a limited usage time.

  - On the server hosting Altair SLC, specify the following
    environment variable:
        SET ALM_HHWU=TRUE

  - Run the following command:
        Almutil -hhwuath -code <auth-code> -system

    Where:
    - <auth-code> is the Altair One authorization code

    This command downloads a configuration file to the default location
    of C:\ProgramData\Altair\altair_hostedhwu.cfg.


- If using an on-site license manager, specify the following
  environment variables:
        SET ALM_HHWU=FALSE
        SET ALTAIR_LICENSE_PATH=<port>@<server-id>

    Where:
    - <port> is the port on the which the license server communicates.
    - <server-id> is the URL of the license server.


- If using a wpskey license file downloaded from the World Programming
  website (worldprogramming.com), you will be prompted to enter your
  license key when you first start Workbench. Alternatively, you can
  apply a license using the following command:

       <installation-dir>/bin/wps -setinit <wps-key-file>

  Where:
  - <wps-key-file> is the path to the downloaded license key file.
