I have encountered this problem on several different Windows 7 systems but it is particularly annoying on my personal laptop. I just replaced the hard drive and installed Windows 7 Ultimate 64 bit. I am now trying to load updated drivers but I get the message that they can only be installed in Administrator mode. I even right click and try the "run as administrator" option and get the same message. I had this same problem with my old hard drive and I tried creating a new profile but ran into the same problem. Please advise.
