On the command line (go to Start->Execute, enter "cmd", click the OK button):

1.) Go to your perl/bin directory (e.g. enter 'cd\perl\bin [enter]'
    if the directory is C:\perl\bin
2.) Enter 'ppm[enter]'
3.) Enter 'search [module name or part of it][enter]'
4.) Enter 'install [number or numbers or number range of modules to in
+stall from 
    the list that appeared]'
5.) Enter 'exit'
6.) Enter 'exit'

And you are done. Here, you are using the Perl Package Manager, which is distributed along with AS Perl, to locate and install precompiled Perl modules. If you do not find your module, have a look at http://ppm.activestate.com.
Hope this helped.
