Is mod_perl installed and activated on your windows server?

This how to permits you to verify it : with your browser go to then an error occurs. error 400 should be this error and it means that mod_perl is installed and activvated.

If uou don't have this error then install mod_perl on the server and activate it in apache conf file.
