I purchased the Alienware M11X labtop and had windows 7 home premium installed...it is supposed to be 64bit however when you bring up the page that shows system information it states it is windows 32bit.exe, is this normal or do I have to alter the bios to have it run in 64bit...or should I call alienware/dell and have them reserch my order to make sure I had the 64bit installed
