You need to distinguish between what are termed "Keys" and what "Values". This may get you started.

#! perl -slw
use strict;
use Win32::Registry;
use Data::Dumper;

my $key;
$HKEY_LOCAL_MACHINE->Open( 
    "Software\\Microsoft\\Windows\\CurrentVersion\\Uninstall", $key 
) or die $^E;
    
my @keys;
$key->GetKeys( \@keys );

for my $subkey ( @keys ) {
    $key->Open( $subkey, my $x ) or die $^E;
    my %vals;
    $x->GetValues( \%vals );
    print Dumper \%vals;
}
