I tried this on three different Windows 7 64-bit machines. On two of the machines, I ran Kies and got the update. I plugged my phone into USB and still it won't connect. On the third machine, I completely uninstalled the Samsung drivers and Kies and rebooted. Then I re-installed Kies. It came up and ran and prompted me to install the update. After I installed the update, when I go to run Kies, it comes up briefly as a task, but never displays a window, and then exits. I don't know what is happening.
