Choose Custom or Advanced installation mode, look for checkboxes that ask for your permission to install third-party apps and uncheck them, read End User License Agreement to make sure nothing else is going to get installed. You can make exceptions for the aps you know and trust, of course. If declining from installing unwanted programs is not possible, we advise you to cancel the installation completely.
