Error deploying a 8.1 app to Windows 10 Mobile RRS feed

  • Question

  • Hi,

    We have an existing Windows 8.1 (Windows Phone Silverlight 8.1) App. If I try to run it on the Windows 10 Phone Device or Emulator I always get the following error message:

    2>------ Deploy started: Project: ****.****.Ui.Phone, Configuration: Debug Any CPU ------

    2>Deploying D:\...\Phone_Debug_AnyCPU.xap...

    2>Connecting to Device...

    2>Installing the application...

    2>Deployment of application to device failed.

    2>Fehler bei der Installation. Wenden Sie sich an den Softwarehersteller.

    • I Use VS 2015 Enterprise Update 1
    • On the Windows 8.1 Emulator everything is OK
    • A new App of the same type created from scratch is working fine on Win 10 Mobile

    Can anyone help me to find the cause of this error?

    A more specific error could help - is there an installation log on the device?

    Thanks for any hint!
