系统安装、授权 & 管理

Installation of any software application should be straightforward, intuitive and, perhaps above all, fast. Furthermore, when you have that software installed, you want to be able to update it as and when you deem necessary, and in a streamlined fashion.

Altium NEXUS provides a fast, efficient Installation Management System that caters for this very need - a system that not only expedites the initial installation process, but lets you handcraft the features available to that soft ware at any time after installation.

Initial Install

Main article: Installing Altium NEXUS

Initial installation of Altium NEXUS is performed using the Altium NEXUS Installer. This wizard-based installer is accessed by running a small (approx. 20.1MB) executable - AltiumNexusSetup<Version>.exe. This executable is downloaded from the Downloads page of the Altium website, and can be saved anywhere on your hard disk.

There are two key elements to installation, definable across the various pages of the installation wizard, allowing you to control what gets installed, and where:

• Design Functionality - allowing you to specify which features are installed initially. The PCB Design option provides the base software and core technologies required to perform PCB design. It is always installed and cannot be deselected. Use the remaining options to tailor the install to suit your needs. This will also have an impact on the initial installation time too!
• Install Location - allowing you to specify the destination folders for the install, in terms of both the Program Files and Shared Documents install locations. These locations become especially important when installing multiple instances of Altium NEXUS.

The installation itself is streamlined and expedient. This allows you to get installed, and up-and-running in the quickest time possible. Once installed, you can further refine your installation in terms of available features and functionality.

Licensing Altium NEXUS

Main article: Altium NEXUS Licensing System

Altium NEXUS includes a streamlined licensing system, enabling you to get licensed and up-and-running with your Altium NEXUS Software in a timely and efficient manner. The system offers various licensing types to meet, and suit, your licensing needs :

• On-Demand - client-side license acquisition is administered by an Altium managed server.
• Standalone - client-side license acquisition is managed by the user through use of a licensing file (*.alf).
• Private Server - client-side license acquisition is administered by the Private License Service of an Altium Infrastructure Server - a free, on-premise server that provides remote Altium product installation and license management.

Extending the Capabilities of Altium NEXUS

Main article: Extending Altium NEXUS

Facilitating the ability to enhance your Altium NEXUS instance, customization of the software is made possible through the concept of Extensions. This is a key concept of the system to understand. An extension is effectively an add-on to the software, providing extended features and functionality. A core set of features and functions are installed and handled transparently as part of the initial install, referred to as System Resources. In addition, Optional Extensions are available - packets of functionality that are optionally installed or removed by the user as required. It is the extension concept that enables the installation to be handcrafted in accordance with design needs.

Customization of an Altium NEXUS installation essentially boils down to management of the available extensions. Install, update, or remove available extensions as and when you need to. Many extensions are available from Altium for use with Altium NEXUS. In addition, and with the Altium Developer extension, you can extend the functionality of Altium NEXUS yourself through use of the Altium NEXUS SDK (Software Development Kit) - creating your own extensions for the software.

And inherent to the Altium Developer extension is the dedicated Developer Interface - the user interface for manging custom extensions. Part of this interface is a publishing feature that enables you to share those extensions securely with a wider audience through release to a global repository of extensions (a Global Extensions Gallery, if you will). This is a cloud-based Altium Repository and opens up the possibility for third party developers to offer and trade extensions for Altium NEXUS, through secure distribution, licensing, and installation of the extensions they craft.

Functionality is added to or removed from Altium NEXUS through installation and removal of optional extensions.

Within Altium NEXUS, management of extensions for the software is performed from within the dedicated Extensions & Updates view, which is accessed by clicking on the  control at the top-right of the workspace then choosing the Extensions and Updates command from the menu.

Accessing the Extensions & Updates area - command central from where you can efficiently manage the functionality available in the software.

Examples

We all can appreciate using examples to get us up and running with specific aspects of the software. At times, such examples showcase a feature or set of features that makes the learning curve a little less steep. In a similar fashion, we like to have access to a pre-developed set of libraries, giving us a boost in the choice of components we can use 'out-of-the-box'.

A selection of example designs are installed as part of the initial installation. In a standard default installation of the software, these can be found in the \Users\Public\Documents\Altium\Nexus2\Examples folder of the installation. Further reference designs, design components, and board templates are available through various sections in the Design Content area of the Altium website:

• Reference Designs are available that showcase functionality in the PCB design domain. These can be downloaded from the Reference Designs section.

Installing Multiple Instances of the Software

Once the base version of Altium NEXUS is installed on a computer (e.g., 2.1.x), you can either update to a subsequent version (e.g., 2.1.x +1), or that subsequent version can be installed as a fresh and distinct instance. The Installation System supports the concurrent installation of different instances of the software. The beauty of installing different version instances is that it enables you to quickly access a previous version directly, and independently, whereas an update effectively replaces the earlier version with the later one.

When running the installer for a subsequent version of Altium NEXUS, an additional page of the Altium NEXUS Installer wizard will be available - Installation Mode. This page gives you the choice of either updating an existing version instance of Altium NEXUS or installing as a separate new version instance. Choose the New installation option to maintain separate version instances of the software on the same computer. Remember to specify different destination folders for the new instance later in the wizard.

To install a separate instance, ensure the New installation option is chosen as the mode of installation.

Installation Folders

There are two important factors that facilitate the installation of multiple individual version instances of the software:

• The ability to specify different destination folders during the install in terms of both the Program Files and Shared Documents install locations.
• The system's use of a Globally Unique Identifier (GUID) for each independent instance. This identifier, which uses the standard 128-bit URN model and is displayed as a 32-character hexadecimal number, is used to uniquely distinguish the application data folders, as well as entries in the registry. When you run a particular instance of Altium NEXUS, the system handles, through use of this identifier, only those files and registry entries specific to that instance.

The following is a summary of the default installation folders for Altium NEXUS 2.x (Windows 7 and above):

• The default main installation path for Altium NEXUS is:

\Program Files\Altium\Nexus2

• Examples, libraries and templates for a default installation can be found in the following directory:

\Users\Public\Documents\Altium\Nexus2

• System application data (including: Extensions, Portal Cache) and security files (license ALF) for a particular instance can be found in the following two directories:

\ProgramData\Altium\Altium NEXUS <GUID>
\ProgramData\Altium\Altium NEXUS <GUID>_Security

For two example instances, the paths might therefore be (inserting example GUIDs): 

\ProgramData\Altium\Altium NEXUS {7DF7280E-CD03-40A9-A6A4-DDD057140F70}
\ProgramData\Altium\Altium NEXUS {7DF7280E-CD03-40A9-A6A4-DDD057140F70}_Security
\ProgramData\Altium\Altium NEXUS {566C1AFA-49CA-4B17-B7CB-70A2042D8DAC}
\ProgramData\Altium\Altium NEXUS {566C1AFA-49CA-4B17-B7CB-70A2042D8DAC}_Security

• User application data files (including: DXP.rcs, UserTools.tlt, AdvPCB.dft, AdvSch.dft, last workspace) for a particular instance can be found in the following directory:

\Users\<ProfileName>\AppData\Roaming\Altium\Altium NEXUS <GUID>

For two example instances, and a user profile of Des.Igner, the paths would therefore be: 

\Users\Des.Igner\AppData\Roaming\Altium\Altium NEXUS {7DF7280E-CD03-40A9-A6A4-DDD057140F70}
\Users\Des.Igner\AppData\Roaming\Altium\Altium NEXUS {566C1AFA-49CA-4B17-B7CB-70A2042D8DAC}

• User local application data for a particular instance can be found in the following directory:

\Users\<ProfileName>\AppData\Local\Altium\Altium NEXUS <GUID>

For two example instances, and a user profile of Des.Igner, the paths would therefore be: 

\Users\Des.Igner\AppData\Local\Altium\Altium NEXUS {7DF7280E-CD03-40A9-A6A4-DDD057140F70}
\Users\Des.Igner\AppData\Local\Altium\Altium NEXUS {566C1AFA-49CA-4B17-B7CB-70A2042D8DAC}

Identifying the Right Folder

For the main program installation and shared documents folders, you have the ability to give those folders meaningful names, which can come in very handy for a machine containing multiple different version instances of the software. But for other folders, they are only distinguished by their GUID. Being able to tell you have the right folder for the right version instance suddenly becomes more difficult. However, help is at hand. By using the Preferences dialog, you can quickly identify the GUID used for the currently open instance of the software and, armed with that knowledge,you can pick the right folder through Windows Explorer.

The GUID can be identified on the follow pages of the Preferences dialog (in a standard default installation of Altium NEXUS):

• Data Management - Backup: in the Path field.
• PCB Editor - Models: in the Directory field for Temporary Mesh Data.
• CAM Editor - General: in the Default log files location field.

Right-click on the entry for Altium NEXUS and use the Uninstall command from the context menu.

Uninstalling the software is streamlined, courtesy of the Altium NEXUS Uninstaller.

Three actions are provided, facilitating varying degrees of 'uninstall' as follows:

• Uninstall - removes the install folders (program files and shared documents locations) but leaves preferences-based folders alone. This enables you to have a build that is not currently installed, but whose preferences can still be reused, for example, by importing into another installed version.
• Remove Preferences - removes just the preferences-based folders, covering system application data and security files, user application data files and user local application data.
• Remove Completely - total removal of the entire installation (i.e. installation folders and preferences folders).

Choose the uninstall action required. If you want to cancel out of the uninstall, click Cancel. To proceed with the uninstall, click Next. The page will change to Uninstalling Altium NEXUS and the chosen action will be processed. Once the uninstall is complete, click Finish on the Uninstallation Complete page of the Uninstaller.
