Created: March 31, 2021 | Updated: August 12, 2021

I run Altium on an offline computer. It is not possible to attach to the Internet or any other network. How do I install Software Extensions & modify the Core Feature Set in this environment.

Starting in Version: 18.0
Up to Version: Current

Solution Details

You can download our Offline Installer Package from a machine that is connected to the Internet, then transfer to your production computer that is not connected to the Internet using a flash drive or other storage media.

Here's a Knowledge Base Article on how to get set up for the Offline Installation Package if you see "Need Offline installer?" instead:

Offline installer
You can then go to Preferences ► System ► Installation to set the radio button for "Offline installation".  Use the browse button to open a dialog to search for the location of the unzipped offline installation package folder.  After that, you should be able to check for updates from the Updates tab of the Extensions and Updates page, or install new extensions from the purchased tab, and even modify the Core Feature Set.

Note that the offline installation radio button option does not check for updates or new extensions regardless of the status of the Altium Connection setting. To perform an update you will need a later copy of the Offline Installation package. - This is what you are doing by following the steps above.
