Request the Link: Log in to your Altium Live Account on the Altium Downloads page. Look for the link that says "Need offline installer?" beneath the primary download button.
Submit Request: You may need to provide a reason for the request (e.g., network security or firewall restrictions). Once approved, a download link for a large ZIP file (approx. 3GB for newer versions) will be provided.
Alternative Contact: If the link isn't immediately visible, you can contact your local Altium sales office or value-added reseller to request the offline installation files. 2. Configure Altium for Offline Installation
Once you have the offline package unzipped on your target machine:
Open Altium Designer and go to DXP (or the user icon) > Preferences. Navigate to System > Installation. Select the radio button for Offline installation.
In the text field provided, use the browse button to select the path to the folder containing the unzipped offline installer (this folder should contain the "Extensions" subfolder). Click OK to save changes. 3. Install the Extension
Go to the Extensions and Updates page (usually found via the user icon or the Home screen). Click the Purchased or Updates tab.
Because you pointed the installation source to your local folder, Altium will now list the extensions available within that offline package.
