I've been trying to install the ADT for Eclipse Classic 3.7 to no avail.

From what I've seen on searches, the general consensus seems to be to update the software, but alas I cannot do that, either.

BELOW: An example of the error message received when trying to update Eclipse, or when attempting to install from a web location.

Some sites could not be found. See the error log for more detail. Unable to read repository at http://download.eclipse.org/eclipse/updates/3.7/content.xml. Cannot assign requested address: JVM_Bind

I followed the troubleshooting recommendations of Google/Android's developer section, and attempted to install ADT via archive.

BELOW: The resulting error from attempting to install via archive.

Cannot complete the install because one or more required items could not be found. Software being installed: Android Development Tools 11.0.0.v201105251008-128486 (com.android.ide.eclipse.adt.feature.group 11.0.0.v201105251008-128486) Missing requirement: Android Development Tools 11.0.0.v201105251008-128486 (com.android.ide.eclipse.adt.feature.group 11.0.0.v201105251008-128486) requires 'org.eclipse.gef 0.0.0' but it could not be found

Now, from what I hear, the inability to update/install via Internet seems to be a proxy-related issue, however I don't believe that I'm under any such thing (I'm just using my computer connected to my home network for this). I'm using the most up-to-date versions of anything I can think of (ADT, Eclipse, SDK Tools etc).

I'm using Windows 7 Ultimate 64bit, and am using the 64bit version of Eclipse Classic.
