Hi,

For Unattended robots, when adapter fails to start within given timeframe, Process Start Failure message shows which require manual intervention. 

I had decompile the OpenSpan.Adapters.Windows dll, i found below method as culprit: 

protected bool ShowStartTimeoutDialog(string name)

        {

          DialogResult dialogResult;

            try

            {

                dialogResult = ((Target)this).get_NotificationService().ShowMessage($"The process {name} failed to start within the given timeframe. Continue waiting?", "Process Start Failure", MessageBoxButtons.YesNo, DialogResult.No);

            }

            catch (NullReferenceException)

            {

                Diagnostic.TraceWarning(TraceCategory.ADAPTERS, "WindowsProcess.ShowStartTimeoutDialog: NotificationService is null - Designer may have been closed while waiting for a process to start.");

                throw new ProcessStartTimeoutException($"The process {name} failed to start within the given timeframe.");

            }

            if (dialogResult == DialogResult.No)

            {

                throw new ProcessStartTimeoutException($"The process {name} failed to start within the given timeframe.");

            }

            return true;

        }

I have tried to turned off all Diagnostic for runtime as well as studio, but no luck.

Either I have to modify dll code (Which is not possible at this time) OR I have to set notification service turned OFF (which either I'm not able to)

Can someone help me to get rid of this?
