Dear SharePoint Geeks,
I’m writing this post to share with you a very interesting PowerShell script called “AutoSPInstaller”, this script developed by Brian Lalancette for an easier SharePoint 2010 deployment process.This script downloads the files required by PrerequisiteInstaller.exe in advance. So, you can complete your SharePoint’2010 installation Offline.
All you have to do is just run the script, download the files, and then use the appropriate command-line switch with PrerequisiteInstaller.exe to allow installation from a locally stored hotfixes and prerequisites.
