The maximum number of developer applications on this phone has been reached

I started a Windows 8 phone application and am trying to use a NEW phone as the device for debugging.

Unable to install application. The maximum number of developer applications on this phone has been reached. Please uninstall a developer application and try again.

I registered the device so I do not know what the issue is. I have read about other people having the same issue but have not found a solution yet.

(Windows Phone App Deployment Issue - see end comment)

Just to make it clear. I have not yet installed any other apps on this phone. It is a new phone I also tried it on another phone of someone I know (but same type Lumia 920) and get the same error.

Edit: After registering on the Windows Phone Dev Center. I still get the same error even after unregistering and reregistering the phone. Strange thing is it says under my account under phones "You haven't registered any phones.", but I did.

Solution

  • When you first use the Developer Registration Tool, it checks DevCenter for your permission level (there are different types of accounts that allow different amounts of unlocked devices and allowed installations).

    Then, the tool unlocks the device and sets those permissions. (make sure the device is connected to the internet by itself, don't rely on the usb connection).

    If you've had recent permission level changes or are changing to a new developer account, you may need to restart the phone to clear the old permissions after removing it from your DevCenter account.

    To summarize:

    1. Remove phone from DevCenter
    2. Open Developer Registration Tool and plug in the phone. Confirm the device is no longer registered
    3. Unplug and Reset the phone (Settings > About > Reset)
    4. Set up the phone, connect to internet
    5. Plug the phone back into the registration tool
    6. Register the device again
