    "Cannot be installed on a windows XP 64 bit operating system" error

    Aidan Bell Level 1

      I've just installed CS5 Master Collection. Everything seems to be fine except for the one program that I need most of all, Premiere. When I try to open the program, I get the error message:  "Premiere Pro CS5 cannot be installed on a windows XP 64 bit operating system. A newer 64-bit operating system is required. Please review the system requirements."

       

      My computer is 64-bit. XP, quad core. I was previously running Premiere CS4 64-bit version without any issues.

       

      Can anyone please suggest what may be going on here?
