a minor add to ikegami's observation (above):

This also depends on what server you're running on the Win platform. The Xitami server, for example, wants a shebang that includes the executable name.ext, thusly:

     #!C/perl/bin/perl.exe

(Correct; it doesn't care which way the slashes tilt) whereas Apache (at least 1.2, etc under w2k) is more "standard" in that it does NOT want the executable named; something I think is also the case in WinNT's built-in.

Suggest you see if your scripts run ok on your windows machine with a *nix-ish shebang.
