Start with mdl application

Is it possibile to start with a mdl application located in a path
containing
spaces?

The command line switch -WA doesn't accept quotation marks.

For expample  'ustation -wac:\program files\company\myapp.ma' doesn't work
and
'ustation -wa"c:\program files\company\myapp.ma"' even crashes ustation on

Vista.
