Adobe Premiere Pro CS5 and Adobe After Effects CS5 32-bit vs. 64-bit support

Windows versions of Adobe Premiere Pro CS5 and Adobe After Effects CS5 require a 64-bit edition of Windows Vista or Windows 7.

This applies to both the standalone versions of the applications as well as the components of Master Collection CS5.

You cannot install or run Adobe Premiere Pro CS5 or After Effects CS5 on any of following operating systems:
•
32-bit and 64-bit editions of Windows XP Home or Professional
•
32-bit editions of Windows Vista Home Basic, Home Premium, Business, Ultimate, or Enterprise
•
32-bit editions of Windows 7 Starter, Home Premium, Professional, or Ultimate

32-bit vs. 64-bit support in Creative Suite 5

If you are using a 32-bit operating system, Adobe recommends that you upgrade to either:
•
64-bit edition of Windows Vista Home Premium, Business, Ultimate, or Enterprise
•
64-bit edition of Windows 7 Home Premium, Professional, or Ultimate

To ease the transition to a 64-bit operating system,

Master Collection CS5 includes a support package that contains 32-bit versions

of Adobe Premiere Pro CS4 and After Effects CS4.
Until you upgrade to a compatible 64-bit operating system,

you can install and use the 32-bit support package included with your purchase.

After you upgrade to a qualified 64-bit operating system, you can install and use Adobe Premiere Pro CS5 and After Effects CS5.

==========

Important: If you are upgrading from Production Premium CS4 or Master Collection CS4

you can continue to use your existing installations of After Effects CS4 and Adobe Premiere Pro CS4,

including  OnLocation and Encore. You do not need to install the 32-bit support package.

If you are upgrading from a standalone version of Adobe Premiere Pro CS4 or After Effects CS4,

you must uninstall it before you can install the 32-bit support package.

This is because standalone versions of Adobe Premiere Pro CS4 and After Effects CS4 do not include Dynamic Link.

To benefit from the workflow enhancements of Dynamic Link

you must install the 32-bit Support package included with your purchase.
