Administrator Account vs Administrators Group????

My default login is a domain account on WinXP pro PC. This account is member of Adminstrators Group for the machine.

Why does CPF treat me like I don’t have Admin priveledges? I could not enter the serial number to register the program until I did a switch user to Administrator …and not when I try to run Updater, it tells me I am need Administrator account to do so. Does CPF not recognize the MS concept of Groups?

I am running ver and trying to upgrade to ver

Do I have to do the log-off - log-on - log-off - log-on stuff again to run the Updater?

I have the same exact problem. I am a domain user who is in the local administrators group and I cannot run the updater.
