Portal Installation Problem

I just tried to download the Portal (Pro version). When I double click the installer, and click OK on the first dialog box, and I hit setup on the second dialog box, it launches my Norton Internet Security 2009 uninstaller. I would like to use the portal so please help me in any way you can. Thank you for your help.

Actually, try disabling norton

I disabled everything in the Norton main menu and it still opens the uninstall screen. *Edit* Dmitri, does the installation write anything to the registry? Because if not then I could install it on a computer that doesn't have norton and then copy the files to the computer with norton....

it doesnt write anything to reg but it does register some dll files. Just uninstall norton lol - that thing is nothing but trouble. I actually got more viruses/computer problems with that installed
