Re: Re: How to obtain a list of software applications installed on a Win based PC?

Hi

I tried this bit of code, however I did not get any information about the installed applications (only 'Done' was displyed).

Can some one shed light on this for me please.

use strict;
use Win32::Registry;
my $Key;
if ($HKEY_LOCAL_MACHINE->Open("Software\\Microsoft\\Windows\\CurrentVe
+rsion\\Uninstall", $Key))
{
    print "\nDone1\n";
    my %ValueList;
    $Key->GetValues(\ %ValueList); # nothing happens here!
    for my $item (keys(%ValueList)) # nor here
    {
        print "\nDone2 $item\n"; 
        print "$item : $ValueList{$item}[2]\n";
    }
    print $Key->{DisplayName}."\n"; 
    $Key->Close();
}

Thanks for the help indeed.

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; }` [download] You may also want to consider Win32::TieRegistry.
