Depending on whether you want to create a new instance or connect to an existing instance, one of the two translations using Win32::OLE should work:

my $appname = "NAMESPACE.object.objectProxy.1";
my $app;

# Connect to the running instance
$app = Win32::OLE->GetActiveObject($appname);

or

# Create a new instance
my $app = Win32::OLE->new($appname);
