Installing the Software

Now reading version 3.2. For the latest, read: Installing the Software for version 5

This documentation page references Altium NEXUS/NEXUS Client (part of the deployed NEXUS solution), which has been discontinued. All your PCB design, data management and collaboration needs can now be delivered by Altium Designer and a connected Altium 365 Workspace. Check out the FAQs page for more information.

Installation of Altium NEXUS is both intuitive and fast, courtesy of the Altium NEXUS Installer. This wizard-based installer streamlines the initial installation process, while letting you choose the initial 'flavor' of the installation, in terms of installed functionality.

This article takes a look at the procedure for installing Altium NEXUS on a computer.

Each major version of Altium NEXUS is released as a separate full installation with unique default installation paths. This allows for side-by-side installation with other major released versions of the software. While it is possible to update to the next point release within a version 'stream', it is not possible to update from one version stream to the next, later version stream.
Need an Offline Installer? For Altium NEXUS, the Offline Installer can be obtained using the applicable link in the Legacy Downloads for Altium NEXUS section of the Legacy Downloads page.

Obtaining the Online Installer

To access the Altium NEXUS Installer, you need to first obtain and run a small (approx. 23MB) executable – AltiumNexusSetup<Version>.exe.  This can be achieved from the Downloads page of the Altium website and can be saved anywhere on your hard disk. To do so, click the Request installer link. A Request Form will appear. If you are an existing Vault or NEXUS user, you can click the link to get the online installer directly. Otherwise, fill in and submit the request form.

Each version of the software has its own dedicated installer.

Running the Installer

Double-click the AltiumNexusSetup<Version>.exe file. The Altium NEXUS Installer welcome page will open.

The installer itself is wizard-based, providing a set of progressive (and intuitive) pages that collectively gather the information to effectively install the version of the software, and its initial feature set, as you require.

Click Next to continue. The following sections provide a summary of the various pages you will encounter.

License Agreement

This page of the Installer presents you with the Altium End-User License Agreement (EULA).

Read and accept Altium's End-User License Agreement.
Read and accept Altium's End-User License Agreement.

Before you can continue with the installation of the software, you must read through, and accept, the terms of this agreement. The agreement can be viewed in different languages, including English (the default), German, Chinese, Japanese, French, and Russian.

Clicking the Advanced button will access an Advanced Settings pop-up window. From here, you are able to specify proxy-settings, if applicable. Click OK to effect any changes and return to the License Agreement page.

Specify the use of basic authentication using proxy settings, as part of advanced options for the install.
Specify the use of basic authentication using proxy settings, as part of advanced options for the install.

After reading the EULA, continue with the install by checking the I accept the agreement box then click Next.

Installation Mode

If you already have Altium NEXUS installed and are running the installer for a subsequent point release within the same version stream (e.g., installing Altium NEXUS 3.1.x, and Altium NEXUS 3.1.x-1 is already installed), 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 it as a separate new version instance. Choose the New installation option to maintain separate version instances of the software on the same computer. Alternatively, choose the Update existing version option, then use the drop-down field to select the specific instance of the software you wish to update.

If you already have a previous installation of Altium NEXUS within the same version stream, you can choose to update that version,
or install as a separate unique instance.

After making your choice of installation mode, click Next to proceed.

Account Log-In

You will now be presented with an Account Log In pop-up window. This means logging in to your Altium Account – to which your valid license is associated – using your AltiumLive Credentials. The reason for this is two-fold:

  • First, it verifies your identity and that the installation of the software is valid as determined by your account and licensing.
  • Second, it provides secure access to the Altium Cloud Repository in which the installation files reside – the files that are required to be downloaded before the software can be ultimately installed on the PC.

Log in to your account using your AltiumLive Credentials.

Select Design Functionality

This next page of the Installer allows 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!

Platform Extensions offer extended functionality to the core platform. Each platform extension is a dedicated package of core platform functionality that has been 'brought out' of the platform and delivered in the guise of an extension. By delivering this functionality as an extension, Altium can deliver updates to that core functionality without having to release an update to the entire platform itself.

Click to enable the functionality you require. As you select and deselect functionality, text at the bottom of the page dynamically updates to reflect the size of the download involved and how this translates to required disk space, once those downloaded files are installed.

Click to enable functionality at the parent level to quickly enable all of its child functionality too.

Remember, no matter what decision you take at initial install, you can add or remove features and functionality at any stage after installation. This puts you in the driver's seat to fully customize your installation in-line with your possibly ever-changing design needs.

After defining what functionality you'd like, click Next to proceed.

Destination Folders

This next page of the Installer allows you to specify the destination folders for the install, in terms of both the Program Files for the software and the Shared Documents that are accessed and used by the software.

Specify where the software and associated documents are to be installed.
Specify where the software and associated documents are to be installed.

These locations become especially important when installing multiple instances of Altium NEXUS. If one or both of these destinations is not currently an empty folder (i.e. devoid of content) you will be prevented from proceeding with the installation until you specify alternate (and empty) destination(s).

The default destinations (Windows 7 SP1 and above) are:

Program Files

C:\Program Files\Altium\NEXUS3

Shared Documents


To specify alternate locations, type the location directly into the applicable field,or click the folder icon at the right of a field and browse for the required destination folder.

Once the install locations are specified, click Next to continue.

Ready To Install

The Installer now has all the information it requires to proceed with the installation. If you need to change anything, click the Back button. If you want to cancel out of the install, click Cancel.

An option is provided to launch Altium NEXUS when you exit the Installer and is enabled by default. Click Finish to exit the wizard.

That's it. You have installed Altium NEXUS on your computer and initially tailored its functionality to suit your design needs. Now it's time to do what you do best and go create that next innovative (and hopefully lucrative) product!

Within Altium NEXUS, the F1 shortcut is definitely worth getting acquainted with. Hover the mouse over anything inside Altium NEXUS - a button, command, dialog, panel, or design object - and press F1 to access documentation for it. F1 also works for specific pages in the Preferences dialog, and specific rule constraint pages in the PCB Rules and Constraints Editor dialog. Also if you're running a command, say you're placing a component and you're not sure how to rotate it, press Shift+F1 for a list of command-dependent shortcuts.

Sign in to Server

After installing and launching your new version of Altium NEXUS, the Sign in dialog will open. Use this dialog to sign in to a target server in which all your managed content is stored.

Sign in to your company's managed content Server.Sign in to your company's managed content Server.

Enter the URL for the target server's address into the Server Address field, and your server access credentials (User Name and Password), then click the Sign in button.

If you don't sign in to your company's Server - for example, you click Cancel in the Sign in dialog - Altium NEXUS will not launch. Conversely, if you are using Altium NEXUS and sign out of your company's Server, Altium NEXUS will also close. Offline (unconnected) mode, if it is permitted by your organization's policies, can be enabled by enabling the NEXUS.OfflineMode option in the Advanced Settings dialog, which is accessed by clicking the Advanced button on the System - General page of the Preferences dialog. You will need to restart Altium NEXUS for the change to this setting to take effect.
 It can be a good idea to enter your server access credentials then enable the Sign in automatically option.
If you already have an Altium Vault (version 2.0 or later), you can still use this as your managed content server and connect to it from your Altium NEXUS installation. Keep in mind that development of the standalone Altium Vault product has ceased at version 3. While the Altium Vault will continue to be supported, it is recommended to upgrade to the Altium NEXUS Server - the native managed content server for the Altium NEXUS product - to take advantage of new capabilities that are being developed in the realms of collaboration, data management, and process management.

Importing Preferences from a Previous Version

After signing in to your managed content Server, Altium NEXUS will continue to launch and the Import Settings dialog will open in which you can choose to import preferences from the most recent previous installation at startup.

Import settings from your previous version's installation.
Import settings from your previous version's installation.

Not only will the preferences be imported, but the user settings also will be copied across - ensuring the new version opens with the same look and feel created in the previous version, even down to the last opened workspace and panel positioning!

If the option to import preferences on initial startup is not taken, don't worry - preferences can be quickly imported at any time from within the Preferences dialog. Click the  button at the bottom of the dialog. The associated menu will list all previous versions currently installed on the computer from which preferences can be imported.

Preferences can be imported from any individually installed version instance of Altium NEXUS.
The benefit of importing at initial startup is getting the working environment looking exactly the way it was set up in the previous installation. Importing preferences at a later stage will only 'restore' a subset of this environment.
