Microsoft Point of Service | Root Element is Missing RRS feed

  • Question

  • Hello!

    When starting the POS software Cash Register Express, I was receiving the error:

    Unable to load global configuration file.  Could not find file 'C:\ProgramData\Microsoft\Point Of Service\Configuration\Configuration.xml'.

    I created an empty Configuration.xml file in this directory, which solved this particular error message.

    However, I now receive the following error on the software's startup:

    Exception while loading global configuration file . Error: Root element is missing.

    I initially thought this may be tied to my version of .NET, but when I went to download the offline installer, It notified me that I was already at or above the downloaded version.

    I'm now thinking that this is likely because the configuration.xml file I made is empty, and may need some information in it?

    This has been occurring since initial setup on a Touch Dynamic Acrobat running Windows 10 Pro.

    How would I go about removing this error? We think it may be causing intermittent freezing of the software.

    Thank you!

  • Hi POSN Travis,

    Thank you for posting here.

    The usual cause of 'Error: Root element is missing' in xml is that the XML document you're trying to load is not formatted properly, more exactly it's missing the root node.

    <?xml version="1.0"?> 

    Besides, here's a reference about Configuration.Xml.

    XML File

    Hope it could be helpful.

    Best Regards,

  • Hi POSN Travis,

    The problem and the freeze seem less relevant.
    It works even without that file.

    If you are worried, try the contents of the file below.
    A minimal configuration that defines nothing.

    <PointOfServiceConfig Version="1.0">

    The location of the file is set in these registry information.

      -> "C:\ProgramData\Microsoft\Point Of Service\Configuration\Configuration.xml"

      -> "C:\Program Files (x86)\Common Files\Microsoft Shared\Point Of Service\Control Configurations\"

    Alternatively, you may define a POS for.NET device with the command "C:\Program Files (x86)\Microsoft Point Of Service\posdm.exe".

    Here is information on how to use.

    Using the POS Device Manager Command-Line Tool (POS for .NET v1.14 SDK Documentation)
