I have installed Expression Web 3, but when I try to enter the serial number, UAC asks for program permission. When I click to allow, the busy circle runs for a second or two, then stops. The serial number is not accepted. However, when I ran EW3 as Administrator, everything went fine and the serial was accepted and I was told that I would not be prompted again. However, now, when I try to run EW3, if I run as normal, I am prompted for the serial, if I run as administrator I am not. I have tried it on my Vista machine and the number goes in first time, without a problem and runs normally thereafter. This has not happened with any other software I have installed on my W7 machine.
