Installing & Managing Altium Designer
Installation of Altium Designer is both intuitive and fast, courtesy of the Altium Designer 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 page takes a look at the procedure for installing Altium Designer on a computer.
Obtaining the Installer
To access the Altium Designer Installer (commonly referred to as the Online Installer), you need first to download and run an executable – AltiumDesignerSetup_<Version>.exe. This executable is downloaded from the Altium Designer section of the Altium Downloads page and can be saved anywhere on your hard disk.
Obtaining the Offline Installation Package
The standard Altium Designer Installer requires an internet connection to complete the installation process. If it is not possible to run the installer from the target PC, you can install Altium Designer using an offline installation package (commonly referred to as the Offline Installer).
First, you will need to obtain the offline installation package. This is a zipped collection of the necessary installables (including extensions), along with the relevant Altium Designer Installer. The latter simply runs, as per the standard internet-based Installer, only getting the required files from elsewhere in the local unzipped content rather than the Altium Cloud repository.
The Offline Installer can be obtained directly from the Altium Designer section of the Altium Downloads page by clicking the Need Offline Installer? link.
Follow the prompts to send a request. Once your request is confirmed, go back to the Downloads page – the link will have been replaced with a ZIP file download link. You may need to sign out of your Altium Account and then sign back in again for the link to change from a question into a download link.
With the Offline Installer acquired, unzip to the required target PC on which you want to install the software.
Running the Installer
-
When using an Online Installer – double-click the
AltiumDesignerSetup_<Version>.exefile. -
When using an Offline Installer – browse to the location on your hard disk into which you have unzipped the offline installation package and double-click the
Installer.exefile.
The Altium Designer Installer welcome page will open.

Initial welcome page for the Altium Designer Installer.
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
to continue. The following sections provide a summary of the various pages you will encounter.
End-User License Agreement
This page of the Installer presents you with the End-User License Agreement (EULA).

Read and accept the 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, French, Chinese, Japanese, Italian, Spanish, and Korean.
Clicking the
button will open an Advanced Settings pop-up window. From here, you are able to specify proxy settings, if applicable. Use the Unified Sign In (Beta) option to choose whether to use a unified sign in process via an external browser on the Sign In stage of installation. Click
to effect any changes and return to the End-User License Agreement page.

Specify the use of basic authentication using proxy settings and unified sign in as part of advanced options for the installation.
After reading the EULA, continue with the installation by checking the I accept the agreement box and clicking the
button.
Sign In
You will now be presented with the Sign In pop-up window. Use it to sign in to your Altium Account to which your valid license is associated. 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 Altium 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.
Signing in is performed using your browser. Clicking the
button will open your default browser with a page from which you can sign in to your Altium Account using your preferred (and accessible) method. Once signed in, the next page of the Installer will automatically open.

Log in to your Altium Account using a unified sign in process.
If you previously opted not to use unified sign in in the Advanced Settings pop-up window, the Account Log In window will appear. Use it to sign in to your Altium Account using your Altium Account credentials, linked Google® or Facebook® account, or your organization's Single Sing-On (SSO) authentication system.

Log in to your Altium Account using credentials, linked Google® or Facebook® account, or your organization's SSO.
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 installation to suit your needs. This will also have an impact on the initial installation time!

What initial functionality would you like in your installation of Altium Designer? The choice is yours! This can be changed later if required.
Click to enable the functionality you require. Click to enable functionality at the parent level to quickly enable all of its child functionality too. As you select and deselect functionality, the 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. Note that the figure given for the amount of downloaded data does not apply to the Offline Installer.
After defining the functionality you would like, click
to proceed.
Destination Folders
This next page of the Installer allows you to specify the destination folders for the installation 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.
These locations become especially important when installing multiple instances of Altium Designer. 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 are:
-
Program Files:
C:\Program Files\Altium\AD<Version> -
Shared Documents:
C:\Users\Public\Documents\Altium\AD<Version>
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
to continue.
Customer Experience Improvement Program
This page is used to choose whether to participate in the Customer Experience Improvement Program. Altium uses the program to enhance our understanding of how our customers use Altium products and services. The data is transmitted via a secure connection so your privacy is protected.

Choose whether to participate in the Customer Experience Improvement Program.
Ready To Install
The Installer now has all the information required to proceed with the installation. If you need to change anything, click the
button. If you want to cancel the installation, click
.

Ready to begin the installation!
To go ahead and proceed with the installation, click
.
Installing Altium Designer
The page will change from Ready to Install to Installing Altium Designer, and the installation will proceed with the required files first being downloaded (from the Altium Cloud Repository when using an Online Installer) or prepared (from the set of files contained within the unzipped Offline Installation package when using an Offline Installer). Progress of this download/preparation is displayed within the Installer itself.

Installation commences by downloading/preparing the required set of install files.
Once the download/preparation of files is complete, they will be installed, again with progress displayed in the Installer.

After the download/preparation is complete, the software is then installed.
Installation Complete
When the installation itself is complete, you have reached the end of the Installer wizard.

Installation is complete!
The Run Altium Designer option is provided to launch Altium Designer when you exit the Installer, which is enabled by default. Click
to exit the wizard.
You have installed Altium Designer on your computer and initially tailored its functionality to suit your design needs. Now it is time to do what you do best and go create that next innovative (and hopefully lucrative) product!
Installing Multiple Instances of the Software
When running the installer for a subsequent version of Altium Designer, an additional page of the Altium Designer Installer wizard will be available called Installation Mode. This page gives you the choice of either updating an existing version instance of Altium Designer 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. Remember to specify different destination folders for the new instance later in the wizard.

If you already have a previous installation of Altium Designer within the same version stream, you can choose to install it as a separate unique instance by selecting the New installation option 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 Designer, 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 Designer:
-
The default main installation path for Altium Designer is:
\Program Files\Altium\AD<Version> -
Examples, libraries, and templates for a default installation can be found in the following directory:
\Users\Public\Documents\Altium\AD<Version> -
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 Designer <GUID>
\ProgramData\Altium\Altium Designer <GUID>_SecurityFor two example instances, the paths might, therefore, be (inserting example GUIDs):
\ProgramData\Altium\Altium Designer {7DF7280E-CD03-40A9-A6A4-DDD057140F70}
\ProgramData\Altium\Altium Designer {7DF7280E-CD03-40A9-A6A4-DDD057140F70}_Security
\ProgramData\Altium\Altium Designer {566C1AFA-49CA-4B17-B7CB-70A2042D8DAC}
\ProgramData\Altium\Altium Designer {566C1AFA-49CA-4B17-B7CB-70A2042D8DAC}_Security -
User application data files (including:
DXP.rcs,UserTools.tlt,AdvPCB.dft,AdvSch.dft, last design space) for a particular instance can be found in the following directory:\Users\<ProfileName>\AppData\Roaming\Altium\Altium Designer <GUID>For two example instances, and a user profile of
Des.Igner, the paths would, therefore be:\Users\Des.Igner\AppData\Roaming\Altium\Altium Designer {7DF7280E-CD03-40A9-A6A4-DDD057140F70}
\Users\Des.Igner\AppData\Roaming\Altium\Altium Designer {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 Designer <GUID>For two example instances, and a user profile of
Des.Igner, the paths would, therefore be:\Users\Des.Igner\AppData\Local\Altium\Altium Designer {7DF7280E-CD03-40A9-A6A4-DDD057140F70}
\Users\Des.Igner\AppData\Local\Altium\Altium Designer {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 that 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. Armed with that knowledge, you can pick the right folder through Windows Explorer.
The GUID can be identified on the following pages of the Preferences dialog (in a standard default installation of Altium Designer):
-
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.

Identifying the GUID used for the active version instance of Altium Designer.
Importing Preferences from a Previous Version or Major Release
After installing and launching your new version of Altium Designer, the Import settings dialog will open. In this dialog, you can choose to import preferences from the most recent previous installation at startup.

Import settings from your previous version's installation.
Not only will the preferences be imported, but the user settings will also 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 project group and panel positioning!
If the option to import preferences upon initial startup is not taken, do not worry – preferences can be quickly imported at any time from within the Preferences dialog. Refer to the Accessing, Defining & Managing System Preferences page to learn more.
Browsing Installed Functionality
Information about your current installation can be readily seen from the Installed page of the Extensions and Updates view. To access the page, click on the Current User control at the top right of the design space, choose
from the menu, and then click Installed at the top of the view.
The page presents the following information:
-
The version of the main Altium Designer platform currently installed, along with the user (and computer name) and Company Account under which a valid license of the software is being used. License/subscription notification information is also presented here. When the license/subscription status requires attention, its overview text is highlighted in red – this can be due to an invalid license, an expired (or soon expiring) subscription, or a portal connection issue.
-
The system extensions currently installed.
-
The software extensions currently installed.
To learn more about extensions, refer to the Extending Your Installation page.

Access the Installed page of the Extensions and Updates page for a summary of what is currently installed in your instance of Altium Designer.
Changing Installed Core Functionality after Installation
During initial installation of Altium Designer, you have a choice over the core design functionality you want to be installed (refer to the Select Design Functionality section to learn more). This choice is not 'set in stone', however, and can be modified at any time after installation. This can be performed in two places:
