Ensure 64-bit builds are served by default to those who choose to covert to 64-bit. Sans Flash Support. Sans the majority of binary Add-Ons. > Phase II: Transition to Universal Installer with guidance as to the benefit of 64-bit (Flash support either via Shumway or Adobe Supported 64-bit plug-in, no wrappers). Wider add-ons support. > Phase III: Transition to Auto Update (with opt-out for 32-bit only).
