The following important announcement was posted today:
Adobe today confirmed that after three full versions of simultaneous support for 32-bit and 64-bit operating systems, Adobe Premiere Pro CS4 and Adobe After Effects CS4 are the last versions to support 32-bit operating systems. Future versions will be native 64-bit applications which will run only on 64-bit operating systems.
Adobe first introduced 64-bit support with Premiere Pro CS2 and After Effects CS2, and has further optimized and architected for 64-bit with each successive release. Most modern PCs are 64-bit capable: virtually all Intel based Macintosh systems support 64-bit applications directly, and Windows users may select a 64-bit version of Windows to take advantage of the hardware capabilities. By focusing future Premiere Pro and After Effects development exclusively on 64-bit, Adobe will be able to deliver video professionals the best available performance, including increased editing speed, rapid switching among tools, and faster rendering–all of which give users more time to be creative.
Customers are being notified to provide fair notice of any changes regarding the operating systems and hardware supported by Adobe solutions. By announcing these changes now, Adobe customers will have time to plan their migration strategy accordingly. To assist in these efforts, Adobe has provided a free whitepaper on the benefits of running Adobe software on a 64-bit operating system today and in the future:
There is no change to Adobe’s other Creative Suite applications. Those who own Creative Suite 3 and Creative Suite 4 will still be able to use the software on 32-bit operating systems and Adobe does not plan to make any changes to support programs currently in place.
