Error occurred when loading data from the service registration folders: Value cannot be null. Parameter name: key


  • I am using HPC 2016 Update 1. 

    I saw this message box when in Configuration -> Services.

    My services run and have no issues.

    May I know if my service registration file has something wrong? Please advise.

              <add type="System.Diagnostics.DefaultTraceListener" name="Default">
                <filter type="" />
