I opt out or use the "direct download." It is a shame you have to take care when using the installer but once in awhile folk claim it installs with them opting out or clicking no. If that happens, supply links so this can be checked out.
I just wanted to say that if i need to download something and then asked while installing if the program should add some toolbar or what ever NO MEANS NO. I CHOSE NO FOR SAP TO NOW MY COMPUTER HAS BEEN RAPED WHILE USING YOUR INSTALLER
