We need to update our Air app to use the Air 1.5.3 namespace to take advantage of it's improved certificate handling. We've specified that namespace application descriptor XML. However, it's not forcing the user to upgrade to 1.5.3 when it's installed like I expected. Instead we're getting this error:
This application cannot be installed because this installer has been mis-configured. Please contact the application author for assistance.
Does it not actually force the user to upgrade (I have incorrect assumptions)? Or is something broken?
