Adobe® CS6 Production Premium or Master Collection and 64-bit edition of Microsoft® Windows 7.
I use a 32-bit version of Windows and want to purchase CS6 Production Premium or Master Collection. What should I do? On Windows, the CS6 versions of Adobe Premiere Pro, After Effects, SpeedGrade, and Encore require a 64-bit edition of Microsoft® Windows 7. If you are using one of the following operating systems, you will not be able to install or run those applications: 32-bit and 64-bit editions of Microsoft Windows® XP Home or Professional 32-bit and 64-bit editions of Windows Vista® Home Premium, Business, Ultimate, or Enterprise
