I have just downloaded and installed xampp (for the first time) on a Windows XP machine and seemed to have started it successfully. When I try to invoke it by giving my browser the URL http://localhost I get the message as a windows popup box:
Apache HTTP Server has encountered a problem and needs to close. We are sorry for the inconvenience...

I should mention that I had been trying to test out a precreated PHP application (refbase) by installing Apache and PHP first myself on my machine (I already had mySQL). When this failed, I was trying xampp as a 2nd attempt.
Many thanks for your help, in advance.
