No Frills - No Junk Installation
You can install RealOne with all the bells and whistles and it is a superb full function media player... but it is not necessary. If you DON'T WANT TO CHANGE YOUR SYSTEM PLAYER DEFAULTS and want to keep your computer working just like it worked before the installation... You can install the minimum player by unchecking all the checked options when installing. When you get to the section that asks what file types you want to associate with RealOne choose none... RealOne will still automatically open RealMedia files and work in your browser.
