what kind of Org are you in?  How are you doing on your apps / tabs / objects & fields limits?  Anything else interesting about your org?  I just did a quick test on a clean developer org -- package installs without issue, so we probably need a little more info to figure out what's happening for you.

I actually registered for the free trial in order to see how the twitter integration can help my organization. tried to install the twitter app on a clean trial application and I keep getting the error message about the avatar icon...

thanks

Hello,

You will need to add the avatar icon to the layout of the object detail page that is generating the error; without the icon on the page, your user does not have FLS on the field.  This is an issue we're aware of, and we do plan to fix it in the next version. 

Please email me with any further issues, or if you'd like to discuss twitter integration and possible use cases! 

All the best,

@lningram

thanks for the answer. how do I add the avatar icon to the layout of the object detail page?

Click "Edit Layout" at the top right hand of the object's detail page (probably the Twitter Conversation object), navigate to Fields, and add the avatar icon field to the layout.  Click to Save.
