I previously had XAMPP installed on a Macintosh Server and was run an open source calendar program. I am now installing on a Windows 2003 server and XAMPP is installed and I am getting to the web pages fine. When I installed the calendar program it tells me that it can't communicate with the CGI.
I also have a commercial purcahsed product that says it can't establish connection with child, check permission or cgi connectivity.
Any idea where to look to solve.
