Altium | Extension Offline Install

Click the button (the gear icon) in the top right corner.

You should now see a list of extensions available from your local source.

If you can’t simply hit "update" within the software, here is the step-by-step guide to managing an Altium extension offline installation. Phase 1: Preparing the Offline Installation Files

Extensions often have dependencies. If you manually copied only one folder, the installation might fail. Always copy the full "Repository" structure provided in the offline installer download.
