Can you check if you're running the Winter 15 Release (what number is in the top left image)? The normal registration form still gives you a Summer 14 release Developer Edition. There is a url for registering a developer preview sandbox, but I can't find it at the moment..

Its not working for existing developer org. Need to register a new org after registering follow this steps.

         - a.   Click Setup | Create | Packages and then click Edit. 
           b.   Click Continue. 
           c.   Type a namespace and then click Check Availability to see if it’s unique.
           d.   Click Review My Selections and then Save
           e.   From Setup, click Develop | Lightning Components.
           f.   Select the Enable Lightning Components checkbox and click Save.
I followed this doc which worked for me.

Thanks Gaurav! After following the steps mentioned by you, I am still not able to see *From Setup, click Develop | Lightning Components *even after creating new dev org.

Hi, The URL https://www.salesforce.com/form/signup/prerelease-winter15.jsp specifies that the pre-released 15 is closed. I have registered this morning, I have a 15 version of the DE but and I don't have access to Lightning Components. Does anyone have an idea? Thanks

Hi Xavier,

Please register at https://developer.salesforce.com/. You will get Winter15 release developer edition by default.

Thanks!!!

I am having the same issue -- I can't see the Lightning Components. This is a new Salesforce developer org, that I just created today -- can anyone clarify what needs to happen? When I go to Develop => Lightning Components, I see only an option to Enable Debug Mode. Thanks for any help/clarification.

Wenda - From Winter '16 on, Lightning Components are automatically enabled so you will not see an "Enable Lightning Components" checkbox in setup. However, Lightning App Builder will say that Lightning Components is disabled by default and will not show any custom components or AppExchange components in the org.

You need to create a custom domain under Settings | My Domain and deploy it to all users. Once this is deployed, you'll be able to see Lightning Components in the App Builder, navigate to standalone apps using components, or test them from Dev Console.

What SamReady said and to add to her point you need to be logged in only from your domain else the Lightning App builder does not get displayed. It keeps showing the login screen again and again.

Hey all,
            got the solution :) you have to add "force:appHostable, flexipage:availableForAllPageTypes" in you component as implements then u can see your custom lightning component in lightning app builder.

PS: mark it as suitable answer and like it if it's helpful for you.
