How To Keep Switch Hidden

[RGT1]

I'm executing Switch from a PowerShell script using the following code.  It appears that the -hide command is being ignored.  Why? I there a way to make this work?

 

    Start-Process $exe -ArgumentList @("-convert `"$SourceFile`"",

                                        "-format `"$Format`"",

                                        "-outfolder `"$TargetFolder`"",

                                        "-overwrite `"ALWAYS`"",

                                        "-settings `"$Settings`"",

                                        "-hide")
