Can't find tools inside SDK

I use windows-7 32bit . But why I download ADT for 32bit & try to open it , it show me this type of dialogue . I can't understand the problem enter image description here

How do I find SDK tools?

To open the SDK Manager from Android Studio, click Tools > SDK Manager or click SDK Manager in the toolbar. If you're not using Android Studio, you can download tools using the sdkmanager command-line tool. When an update is available for a package you already have, a dash appears in the check box next to the package.

How do I fix SDK tools folder is missing?

Quick fix: Go to the Tools –> SDK manager –> SDK tools. Deselect Hide obsolete packages option on the right bottom and further install Android SDK Tools(obsolete). A new folder named Tools is now generated in the SDK directory.

Go to SDK manager, then open it, then there are some tools in API versions and extras... Download the packages then restart Eclipse...
