in reply to How to find GUID of Typelibrary for a given OLE Object?

I believe the following is the kind of thing you're after:
package Typelibs; use warnings; use strict; use Win32::OLE::Const; # list of all registered type libraries my @Library; Win32::OLE::Const->EnumTypeLibs(sub { my ($clsid,$title,$version,$langid,$filename) = @_; return unless $version =~ /^([0-9a-fA-F]+)\.([0-9a-fA-F]+)$/; my ($maj,$min) = (hex($1), hex($2)); push @Library, [$clsid,$title,$maj,$min,$langid,$filename]; }); sub ExistsTypeLib { my $typelib = shift; for my $lib (@Library) { return @$lib if($lib->[1] =~ /^$typelib/); } return undef; } 1;

You can then call TypeLibs::ExistsTypeLib('Microsoft Excel') and it should return a list consisting of the ClassID, Title, Major Version Number, Minor Version Number, LanguageID, and Executable Filename.

I now have a modified version to check whether Outlook is installed for my Outlook CPAN modules.
