Well, the most likely reason is that your script is running under a different Perl than you installed it for. So, first, you should follow Corion's advice, finding where cpan did put that module. You can search your whole C: drive with 
dir /b /s C:\Read.pm

[download]
and you should match the result with the Perl versions that are on same:
dir /b /s C:\perl.exe
