Try instead LoadFile "C:/Path/to/Apache2/bin/libarpeq2.dll" LoadModule apreq_module modules/mod_apreq2.so
I get the following now: C:\Program Files\apachefriends\xampp\apache\bin>apacheSyntax error on line 177 of C:/Program Files/apachefriends/xampp/apache/conf/httpd.conf: Cannot load libapreq2.dll into server: The specified module could not be found.
