Install OCSNG on Windows. File does not exist C:/xampp/htdocs/ocsinventory

I install OCSNG Windows Server on Windows 7 Ultimate x86 under VirtualBox.
I install OCSNG Windows Agent 2.3.0.0 and run it on the same Virtual PC. I set server URL: http://localhost/ocsinventory
But data does not collect.
Apache error.log contain messages: "File does not exist C:/xampp/htdocs/ocsinventory".
What's wrong? How to fix it?
