Android ADT version update throws error status

Issue

I am writing this after struggling a lot with updating my ADT. I have tried using different eclipse, android sdk everything, but still it says me that Android SDK requires android developer toolkit version 17.0.0 or above, current version is 11.0.0.v201105251008-128486.

I referred question mentioned here Android SDK requires android developer toolkit version 17.0.0 or above

But when I checked for updates again it displays a warning message stating that

Warning: You are installing software that contains unsigned content. The authenticity or validity of this software cannot be established. Do you want to continue with the installation?

along with the OK and Cancel buttons.

I got fed up of this, can any one tell me how to resolve this?

Thank you

Solution

I don't know what is happening wrong with the eclipse or android sdk. I deleted literally everything except my workspace. Then installed again and now it works fine.
