⚠️ : ArcGIS Desktop 10.8.x reached its end of life on March 1, 2026, and is no longer receiving security updates or support from Esri. It is highly recommended to plan a migration to ArcGIS Pro for continued support and access to modern GIS workflows.

Locate and run setup.exe (usually found in the ArcGIS_Desktop_108_xxxxx.exe extracted folder).

Version 4.5 or higher is required.

With ArcGIS Desktop 10.8 now at its end of life, it is advisable to begin evaluating ArcGIS Pro for your future GIS needs while using this proven version for legacy project compatibility.

Requires a license manager (License Server).

Setup.exe /qb ACCEPTEULA=yes SOFTWARE_CLASS=Editor SEAT_PREFERENCE=Fixed DESKTOP_CONFIG=TRUE INSTALLDIR=D:\ArcGIS\Desktop10.8 ENABLEEUEI=0

(It works, but it feels like a chore from 2012).
