you're doing:

$lista= $Registry->Connect( "$ip", "LMachine" )
[download]

at this point, $lista contains the Registry of the remote machine. then you do:

$lista=$Registry->{"HKEY_LOCAL_MACHINE/..."}
[download]

so you're opening a key on the local registry ($Registry).

it should probably be something like:

$Remote = $Registry->Connect( "$ip", "LMachine" ) or die "blah...\n";
$lista = $Remote->{"HKEY_LOCAL_MACHINE/..."};
[download]
