I have the same problem as jwsrcp.
I am running the 32 bit version instead of the 64 bit version.
I have uninstalled SeperAntiSpyware using the downloaded unstaller from the web site, reinstalled the latest version of SAS downloaded from the website, and set the parameters to "run as administrator." Everything is fine until I reboot my computer. When SAS reinstalls on bootup, it does not reinstall as administrator, so I get the "run as administrator" prompt when I try to download updates.
I have posed this problem to SAS support, and have not received any solution. I have suggested to them that someone write a autoexec.bat file with the proper switches set that would load SAS as administrator version at bootup. To my knowledge, this has not been done yet.
