I found it simpler at times to first uninstall all the 7 components:
-Android DDMS -Andoid Devlopment Tools -Android Hierarcy Viewer -Android Native Development Tools -Android Traceview -Tracer for OpenGL ES -Google App Engine Tools for Android(If installed)
Then download the latest ZIP/Archive.
Install the Archive from Help->Install New Software->Add->Archive Select the downloaded ZIP, provide a name for it and follow the standard installation process.
