Windchill 10.2 : HTTP Server doesn't start

Hi,

I've installed Windchill 10.2 on a Windows Server 2012 + SQL Server 2008 server. Everything run fine. And just after the installation, Windchill started. Then, I rebooter the server, my goal is to make Windchill automatically started.

I've created the Windchill DS service. But the problem is when I run "windchill start", everything seems to run fine, except there is no httpd process on the computer, so no web server.

I've found nothing in the logs and no script to run it. Thanks for the help.
