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.

Are you posting in the right place? Check out Where do I post X? to know for sure.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).

are good places to start.
