Air Auto Update Error -- Flash Builder Burrito.

Report · Feb 07, 2011

This is my first attempt at this, so I may be missing something simple.

I'm not having any luck getting an Air app to automatically update.

If I manually go to http://localhost/air1/air1.air and redownload the file I will get a popup that asks if I want to update the app, but when I say ok I get this error.

"There was an error checking for updates. Error# 16816"

I haven't found a reason yet,

Any ideas?
