Hi guys I was wondering if anyone could help me. Now before anyone asks me why I am trying to use and older av suite it because I am just trying to learn how to use orca and how to bypass the prerequiristes for Microsoft windows installer checks using my second system that I just use to experiment with but my main system is untouched everything on it is good and untampered with all up to date software. This system however I just use to muck around on and practice and experiment with software I am trying to install Norton Internet Security 2007 on my windows 8 Pro x64 second machine Previously it worked on my windows 7 x64 ultimate just by using compatibility mode as vista now I am getting the following message with win 8 "Setup cannot continue because there was a problem authenticating your Microsoft Windows Installer" when I checked the log file in the %temp% directory this is what I got. 2012-11-20-00-36-43-664 : 0x05C0 : Product reboot state = 0 2012-11-20-00-36-43-664 : 0x05C0 :
