Operating System Compatibility
Adobe’s official system requirement information lists only Windows 7 and Windows Vista with Service Pack 1 as compatible with Premiere Pro CS5 and CS5.5. The Desktop mode in Windows 8, however, works very similarly to Windows 7 and supports the same software. Adobe has also specifically tested various older Creative Suite products – even including Photoshop all the way back to CS3 – using Windows 8 with the 8.1 update and encountered no major issues.
64-Bit Requirement
Starting with CS5, Adobe Premiere Pro requires a 64-bit version of Windows which in turn requires a 64-bit processor. This limitation does not apply to all Creative Suite 5 products – only Premiere Pro and After Effects. To check whether you have a 64-bit version of Windows 8, press “Windows-X,” click “System” and check the line reading “System type.” Writer Bio
