Because no space in this world is immune from advertising, you're about to see ads start popping up in software installers. OpenCandy, the company providing the technology says software developers can use their software in one of two ways. During the installation process, users will either see:

1. An option to install a similar application
2. An ad

But if you ask me, both options are an ad. Not that there's anything wrong with that. In one case, you may see a paid advertisement, while in another case you may see a recommendation to download an application. Whether the developer of that application paid to get the software title in front of you or not, there's clearly an exchange of value taking place here.

Anyway, the offers to install additional software are always opt-in. So you won't accidentally install unwanted software just by clicking Next over and over. And the way OpenCandy handles additional software installations is actually pretty nifty. Near the end of the install process, you're asked if you want to add an extra application. If you choose yes, the first installer will finish up, and then you'll automatically download the new program and its installer will launch.
