The Altium extension offline install process is not merely a workaround for a missing internet connection; it is a professional methodology for ensuring software stability and security compliance.
By mastering the Export/Import workflow for single machines or the Repository Mirroring for enterprise fleets, you transform Altium Designer from a cloud-dependent tool into a resilient, air-gap-capable platform.
Remember the golden triangle of offline success:
With this guide, you can now confidently deploy Altium’s most powerful extensions into the most restricted environments on earth—from a defense contractor’s SCIF to a nuclear reactor’s control room. Keep designing, even when you’re disconnected.
Installing extensions in Altium Designer usually happens through the cloud. But if you’re working in a secure environment or on a machine without internet access, you’ll need to go the manual route.
Here is a quick guide on how to handle an offline installation. How to Install Altium Extensions Offline
The trick to offline installation is the Local Installation Service. You essentially bring the "cloud" to your local machine or network. 1. Download the Offline Installation Files
You cannot download individual extensions directly from a browser.
You must use the Altium Offline Installer (available via the Altium Downloads page).
This package includes the base software plus the standard extensions. 2. Set Up the Local Repository
Extract the installer files to a shared network drive or a portable USB.
Look for the Extensions folder within the installer package. Ensure you have the .aux or repository files ready. 3. Configure Altium to Look Locally Open Altium Designer. Go to DXP > Extensions and Updates.
Click the Configure button (the gear icon in the top right). Under Update Options, uncheck the box for "Altium Cloud."
Select Local Installation Service and point the path to your offline folder. 4. Run the Installation Go back to the Purchased or Installed tab.
You should now see the extensions populated from your local folder. Click the Install icon on the specific extension you need. Restart Altium to finalize the process.
💡 Pro Tip: If you are in a corporate environment, it is much easier to set up an Altium Infrastructure Server (AIS). This allows one admin to download updates once and distribute them to every offline workstation in the office. If you'd like, I can help you with more specifics:
Installing Altium Designer extensions in an offline environment requires using the Offline Installation Package, which serves as a local repository for both the core software and its optional extensions. 1. Obtain the Offline Installer Package
Because Altium Designer typically retrieves extensions from the Altium Cloud, you must first download a complete offline set from a computer with internet access.
Log in: Visit the Altium Downloads page and sign in with your AltiumLive account.
Request the Installer: Look for the link titled "Need Offline Installer?".
Download: After submitting a brief request, the link will eventually change to a ZIP file download link (you may need to sign out and back in to see the update).
Transfer: Transfer this ZIP file (typically ~3GB) to your offline machine via a USB drive or local network and unzip it to a known directory. 2. Configure Altium Designer for Offline Use
Once the package is on your target machine, you must redirect Altium Designer to use this local folder instead of the internet.
Open Preferences: Navigate to DXP > Preferences (or the gear icon). Installation Settings: Go to System > Installation.
Set Source: Select the radio button for "Offline installation".
Browse to Source: Use the browse button to select the root folder where you unzipped the Offline Installer package. Apply: Click OK to save these settings. 3. Install Extensions Offline
With the local path set, you can now manage extensions without an active internet connection.
Access Extensions Management: Go to your user profile icon (top right) and select Extensions and Updates. Select Extensions:
Purchased Tab: Browse here to find available extensions. Since you are pointed to the offline source, Altium will list what is included in that local package.
Available Tab: This tab will now list extensions found in your local repository.
Install: Click the download/install icon on the specific extension you need (e.g., specialized importers/exporters or simulation tools).
Restart: After the installation completes, restart Altium Designer to activate the new functionality. 4. Important Considerations
Updates: The "Offline installation" setting prevents Altium from checking for new online updates. To update extensions later, you must download a newer version of the entire Offline Installer package.
Licenses: Ensure you have already added your Standalone License file (*.alf) or are connected to a local Private License Service, as the software still requires valid licensing to run these extensions. AI responses may include mistakes. Learn more
For users working in high-security environments or with limited internet access, Altium Designer offers an Offline Installation Package
