Use single quotes in your Shell command:
eg: Shell '%COMSPEC% /c yourcommand -arg "this and that"'

Use %COMSPEC%, not CMD

Build a command string instead of placing everything in the Shell statement
$Cmd = 'blah-blah'
$Cmd = $Cmd + 'More stuff'
$Cmd = $Cmd + 'even more "stuff here"'
; Next 2 lines for debugging
'Running:' ?
$Cmd ?
Shell $Cmd

We really don't need to see the entire HEX string - please trim your original post to prevent the long lines.
