I got an Alienware Area 51 from a friend last week and I'm having trouble installing Alienware Command Center. I've got Windows 7 installed on one hard drive and Windows 8.1 on a second hard drive. On both OSs I'm getting an error when I run the installer saying "The installation package is not compatible with this platform." I've downloaded and attempted to install "Alienware_Command-Center-Des_A05_R308775.exe", which from other posts seems to be the latest version that supports the Area 51.
