Can I run 64-bit programs on a 32-bit computer?
If the program is specifically designed for the 64-bit version of Windows, it won't work on the 32-bit version of Windows. (However, most programs designed for the 32-bit version of Windows do work on the 64-bit version of Windows.)
Device drivers designed for the 64-bit version of Windows don't work on computers running a 32-bit version of Windows. To learn how to check for drivers, see Update a driver for hardware that isn't working properly or go to the device manufacturer's website. You can also get information about drivers by going to the Windows 7 Upgrade Advisor webpage.
Você precisará obter uma versão de 32 bits do Adobe After Effects. - Nessa situação, você pode instalar o CS4 para 32 bits entrando em contato com o suporte ao cliente com a chave serial CS6 - você deve receber uma chave válida.
This package has been removed in the CS6 versions of these suites. But it's available upon request for customers who have other mission critical programs that require a 32-bit OS. Adobe offers this continued legacy support for a limited time. If you use a 32-bit OS, begin transition plans now.
Vale a pena notar que você tem 6 GB de RAM instalados, mas com um SO de 32 bits não é possível resolver tudo isso. Pode valer a pena considerar a instalação de uma versão de 64 bits do Windows 7 para resolver toda a sua RAM disponível, bem como instalar este software. O Windows de 64 bits é compatível com programas de 32 bits, mas não vice-versa.
