A new TechNote article has been added to the Adobe Knowledge Base. This article describes how to install all of the Acrobat 8 patches all at once.
Acrobat 8 supports Patch Sequencing. This is a technology that lets the Windows Installer (among other things) to determine which order patches are applied and also allows patches to be applied during installation. Adobe Systems has provided the Adobe Bootstrapper (setup.exe) which can automate a lot of this.
