Gmail contextual gadget deployment

Question

Seems that UI was changed once again and I cannot deploy "Hello world" Gmail Contextual Gadget following the steps provided by Joc (Gmail contextual gadget):

• There are no "Allow individual install" on the step #7
• I also cannot find "Test installation flow" (step #10)
• The gadget is not listed in the Marketplace list (step #11)

Could you please assist me?

Answer 1

• In google apps marketplace sdk API, in tab configure, after Application info section, there is a checkbox Enable individual install
• After you save changes at the bottom of this page there is a button Test installation flow at the top of the page. I admit, sometimes it doesn't appear to me.
• the Marketplace list I can't reach at the current time. I don't know how to be an administrator or how to make a free trial domain (although it's written in apps.google.com)
