Ports 80 or 443 already in use installing apache2.2 service failed

Answer: It's a known issue that if Skype was installed before XAMPP it will occupy port 80 which is the port that XAMPP needs to communicate with your Internet connection. There's an easy fix for this problem. Solution: Open up Skype and go to Tools and select Options. From the list that appears select Advanced and then Connection. There will probably be a check mark inside where it says Use port 80 and 443 as alternatives for incoming connections just unchecked that box and save your changes. SQL Server Reporting Services(MSSQLSERVER) may also use 80 port solution: right click on Computer then choose manage > service and application> services> select SQL server reporting services from list and than double click on automatic from start up column choose manual than ok and than click stop service from top Web Development Agent Service may also use 80 port.
