There could be lots of things wrong. It sounds like your script is fine, but just in case it isn't (maybe some use statements are failing - they get executed before the rest of your code, as if they were wrapped in a BEGIN{} block) you could try making this your first statement:

use CGI::Carp qw(fatalsToBrowser);

This will catch any runtime errors and redirect them so the browser can see them.

However, more likely it is a configuration error. Check with a very simple test script to see if it works, e.g. 

print "Content-type: text/html\n\n";
print "<html><body>OK</body></html>";

if that fails, it is an IIS config problem.
