InstallAware

Is there a pre-defined variable for the "user's startup folder?" I want to install a shortcut into the user's Startup Folder so that my program launches whenever the user starts Windows? What's the best way to do this?

You can retrieve that folder via "Get Folder Location", look for the option Start Menu->Startup Group.

Actually the best way to do this, is to put a Registry key on the "Run" key section of HKLM\\SOFTWARE\\Windows\\CurrentVersion\\ or HKLU\\SOFTWARE\\Windows\\CurrentVersion\\, depending if you want to start the program only to the user who installed it, or for all of them..Use "Write Registry" function.
