Invalid command 'Require', perhaps misspelled or defined by a module not included in the server configuration
The Require directive is supplied by mod_authz_core. If the module has not been compiled into your Apache binary, you will need to add an entry to your configuration file to load it manually. You can check which modules are compiled in with httpd.exe -l.
If the module is not compiled in, load it with a configuration line similar to the following:
LoadModule authz_core_module "<apache install dir>/modules/standard/mod_authz_core.so"You will need to adjust the path for your system of course, and on a Windows box the library may well be a dll rather than an so file.
