I realise this is an old thread, but I have a user In Japan who has an Edge 1030. I got him to send details of the device firmware, etc. It's 11.10 and it says it supports Connect IQ SDK 3.2.4. I have three apps in the apps store, two of which he has installed on his device. The manifest for these apps specifies English, min SDK of 2.4.0 and the Edge 1030 device. He wants to install my third app (In The Zone) which is an updated and combined version of the other two apps. The manifest for this app specifies English, min SDK of 3.2.0 and the Edge 1030 device (The app shows weather and was built with Strict Type checking). The user cannot install "In The Zone" - he gets the message which is the subject of this thread. He can see it in the Connect IQ Store. I can't see why the app won't install on his fully firmware updated device, when the other two apps do. Any clues?
