Which software sites should I have in Eclipse Indigo?

Question

I just installed Eclipse Indigo (Service Release 1). For some reason my "Available Software Sites" list is empty. Why is this? What sites should I have in the list? Everything I've seen online suggests that there are a number of defaults that should be present.

ETA: Running as administrator (as per this question) seems to have made sites show up.

Answer 1

As per edit and this question, it turns out I needed to run as administrator to show the available sites.

Answer 2

primary update site is http://download.eclipse.org/releases/indigo/

Please check this out: Window -> Preferences ->Install/Update -> Available Software sites

Make sure that requested sites are checked
