Thanks to the answers to my previous questions, I have won the battle with Panda Antivirus, and started to install XAMPP.
As directed, I ran "setup_xampp.bat", which appeared to complete successfully.
But when I run ".....\apache_installservice.bat" (yes, I am using Windows XP Professional), I get the following error message:
"<OS 10048> Only one usage of each socket address <protocol/network address/port> is normally permitted. : make_sock: could not bind to address 0.0.0.0:443, no listening sockets available, shutting down.
Unable to open logs."
Again, any assistance will be appreciated!
