After Effects

Does After Effects still support 32-bit operating systems?

No, because the performance benefits of native 64-bit support make it the best choice for the demanding technical requirements of working with video, particularly HD and higher resolution content. Offering only 64-bit support enables Adobe to optimize performance even further. If you buy the Windows® version of Adobe Creative Suite® 5.5 Master Collection or Production Premium software and you do not yet have a 64-bit operating system installed, you can use After Effects CS4 for Windows, which is included, until you upgrade. (Note that After Effects CS5.5 and Adobe Premiere® Pro CS5.5 are the only CS5.5 components that require a 64-bit operating system.)

I am a Windows user with a 32-bit version of Windows. Where can I find more information about the 32-bit compatibility options for After Effects CS5.5?

If you purchased a copy of CS5.5 Production Premium or Master Collection, visit the 32-bit compatibility page for more information and detailed installation instructions. If you purchased a standalone version of After Effects CS5.5, you will need to upgrade your computer to meet the minimum system requirements before installation. Visit the system requirements page for more information.
