Which Galileo package did you download? If you want to do C/C++ development you might just want to download the "Eclipse IDE for C/C++ Developers" package, that is usually a better bet than adding capabilities to another package. And yes you can have multiple Eclipse instances on your disk, and even running. I do it all the time - I have several Eclipse instances for Java and one for PHP.
