Is there a setup.exe I can use to uninstall features?

Hi All,

Is setup.exe only on the install disc?  I want to uninstall some SQL Server 2012 features--like an instance or SSIS--but I hurt myself recently and I don't want to pull down a heavy box full down from a high shelf.

This is assuming I'm allowed more than one dumb question per year, and thanks for your help.

Thanks,
Eric
