The End of an Era: Navigating the ArcObjects SDK 10.8 Download
If you are looking for the ArcObjects SDK 10.8 download, you are likely maintaining critical legacy systems. As of March 1, 2026, Esri has officially retired the ArcGIS Desktop series (including ArcMap 10.8.x), marking the end of the ArcObjects era.
While the software is in "Mature Support," meaning no new features or major patches are coming, many organizations still rely on these tools for their existing COM-based extensions. Where to Find the Download

ArcObjects is typically bundled under "ArcGIS Desktop" or "ArcGIS Engine".
