Win32::API comes loaded with Activeperl by default, so you shouldn't really have to install it.

Your code works fine for me.

My wild, stab in the dark guess, based on prior experience, is that you upgraded your Activeperl setup, but didn't bother uninstalling the old one first. This seems to lead to modules being invisible. The solution is to uninstall all the old versions and then install a new one.
