I have installed XAMPP on Windows successfully. But, whenever i starts Apache server then found following error from XAMPP Control Panel:
The most common problem that you are running another program which is blocking port 80 or 443. If you have installed Skype, then you have found this problem.
First Method:
1) Open Skype
2) Go to Tools
3) In Advanced settings click Connection option
4) Uncheck option – Use port 80 and 443 for additional incoming connections
5) Click on the Save button same as given image, see below:
6) Now Restart your system.
