Aptana Studio 3 plugin doesnt get installed properly on Eclipse Juno

I have Eclipse Juno running on 64bit windows 7, I tried installing Aptana Studio 3 plugin for eclipse. The installation goes fine, and aptana plugin shows up in the Installed plugin list too as follows: enter image description here

But thats it! I cant see Aptana anywhere else in eclipse, not in preferences,perspectives, views nowhere! A strange thing i noticed was that while installing aptana plugin, i wasn't shown any security warning dialogue box telling me that its an unsigned plugin, something that i was expecting.

Has anyone else faced this problem before? Am i going wrong anywhere? please help.

EDIT: The same problem persists with Eclipse Indigo too.

Solution

Solved it myself! after looking at the error logs i realized that i had previously added a archive file to install aptana from disk (failed attempt).It was mentioned in the logs at several places, dont know why, but when i removed that repository Aptana installed fine on eclipse. :)
