I have just installed XAMPP and everything works fine except that I can\'t get apache to run. It seems that port 80 is the problem, I have disabled Skype to use port 80 but
There are 2 ways to solving this problem.
#Listen 0.0.0.0:80
#Listen [::]:80
Listen 80
by
#Listen 0.0.0.0:81
#Listen [::]:81
Listen 81

If you didn't find “World Wide Publishing Service” there then go to "Run>>resmon.exe>> Network Tab>>Listening Ports" and see which process is using port 80

And from "Overview>>CPU" just Right click on that process and click "End Process Tree". If that process is system that might be a critical issue.
