Installing ArcGIS 10.8: A Step-by-Step Guide

3. Installation Procedure

3.1 Pre-Installation Steps

1. Uninstall older versions of ArcGIS Desktop (10.x may co-exist with 10.8, but avoid conflicts).
2. Temporarily disable antivirus and Windows UAC (User Account Control).
3. Run Windows Update to ensure all system patches are current.
4. Log in as a Local Administrator.

Single Use: Click Authorize Now. Select "I have installed my software and need to authorize it." Enter your authorization code (starting with ESRI...) and follow the prompts to authorize via the internet. install arcgis 108

2.2 Pre-Installation Steps

1. Disable Antivirus Temporarily: Real-time scanning can corrupt the deployment of ArcGIS system files. Disable Windows Defender or third-party AV until the installation finishes.
2. Close All Microsoft Office and Browser Tabs: The installer checks for file locks. Word or Excel can cause conflicts.
3. Check for Older Versions: If you have ArcGIS 10.0–10.7 installed, you can upgrade. If you have ArcGIS 9.x, you must uninstall it first.
4. Run Windows Update: Ensure all critical OS updates are installed, especially for Visual C++ Redistributables.
