Eclipse not working with ADT Plug in

Question

I recently bought an SSD(Solid state drive) just for Eclipse. I wanted to have a complete new fresh installation of ADT along with eclipse, so I downloaded the bundle from here.

I have downloaded it, extracted, then went into the eclipse folder and ran "eclipse". When the program is opening, I am not presented with this:

Like it should, but I am presented with this:

Then once the program is loaded up, it seems like there is no ADT Plug in installed anywhere. I have tried going to Help --> Install new software --> Add --> then downloading it again via https://dl-ssl.google.com/android/eclipse/ but it just says:

So I tried going to Help --> About --> Installation details then updating, then it prompts me with this:

If anyone would be able to help me out with this, that would be great.

Answer 1

Option 1 -
This is because previous version of ADT cannot be updated..
you will have first uninstall previous version

Go to Help > About > Installation Details > Select ADT
and uninstall.. and after that do whatever you have done till now (install software https://dl-ssl.google.com/android/eclipse )

(This can be result in error Cannot backup eclipse.exe )

Option 2 -
Download new Android Sdk, which comes with new ADT installed.
