I've been using xampp for years now with my XP home and never got any problem at all. However, I just got an XP Pro with IIS installed and when i tried to install XAMPP, it said that apache cant be installed because port 80 or 443 is not available. I suspect it is because of skype and IIS. Since I also need skype and IIS, is there any way for me to run all at the same time? or if it comes to worse, maybe i can switch on/off between those applications according to what i need at the present ? Thanks.
