I too am getting this error at the system setup stage error 406 An appropriate representation of the requested resource /testsite/zc_install/index.php could not be found on this server.

I have tried renaming the .htaccess file but to no luck and also reinstalling the zc_install folder

I can pm across the true path that is failing. Thanks for any help. The fileset is 1.3.7 for a fresh install
