$dirs{$File::Find::name} = 1;

in sub dir_names is bogus. The following increment line does all the work required.

Update: Oh, and you probably want to compare just the directory name instead of the full path so you probably want to use $_ for the hash key. Actually, even better is to keep a list of full paths by directory name so you can see the full path of all duplicated directories:

#!/usr/bin/perl
# dirdupes

use strict;
use warnings;
use File::Find;
#*****************Path Variables**********************
our $testpath = 'E:\scratch~~\Lin\App\KuraCloud';
#*******************************************************

my %dirs;

find(\&dir_names, $testpath);

my @dup_dirs = grep {$dirs{$_} > 1} sort keys %dirs;

foreach my $name (@dup_dirs) {
    next if @{$dirs{$name}} == 1;

    print "$name:\n";
    print "  $_\n" for @{$dirs{$name}};
}

sub dir_names {
    return if ! -d || ! /[IPD]\d{8}$/;
    push @{$dirs{$_}}, $File::Find::name;
}
