Recently I was just trying to run XAMPP Lite on my Vista PC. XAMPP is a cool little utility that lets you run Apache, MySQL, PHP, and Perl all from a USB drive and without installing anything to your windows computer. Although I could get MySQL to start, I could not get Apache to start up. I did not have IIS installed, which could have caused a conflict with Apache, since both are web servers.
I ran xampp-portcheck, the port check utility that was included with XAMPP. It showed that ports 80 and 443 were being used by SYSTEM (see below).
RESULT
——
Service Port Status
==================================
Apache (HTTP) 80 SYSTEM
Apache (WebDAV) 81 free
Apache (HTTPS) 443 SYSTEM
MySQL 3306 free
FileZilla (FTP) 21 free
FileZilla (Admin) 14147 free
Mercury (SMTP) 25 free
Mercury (POP3) 110 free
Mercury (IMAP) 143 free
I opened a browser and it reacted as if I had a web server on localhost. The page was blank.
I decided to view the HTML source code and found the following:
<!DOCTYPE HTML PUBLIC “-//W3C//DTD HTML 4.0 Transitional//EN”>
<HTML><HEAD>
<META http-equiv=Content-Type content=”text/html; charset=windows-1252″></HEAD>
<BODY></BODY>
<META content=FUGCLQURCL name=SKYPE_FRAMEID>
<META content=FUGCLQURCL name=SKYPE_FRAMEID></HTML>
I noticed that at the bottom of the source code in a META tag, there was a value of SKYPE_FRAMEID. I decided to stop Skype and sure enough Apache was able to start.
I then started Skype and both programs are able to run.
Skype is a smart program. Since most firewalls allow ports 80 and 443 for web traffic, Skype uses those ports if they are available. If 80 and 443 are in use, Skype will choose other ports to use.




Thanks So Much I Thought That The Error Happen Because I Installed Vmware But I Never Expect That Skype Is The Reason .
Hi I have a similar problem in that my apache wont start either, it was all working and I ran the port check (exe file included with XAMPP) it shows port 80 open.
This all happened after a windows update happened and I cant get apache to run. I have googled with no real luck. I know sometimes the firewall can be an issue blocking certain ports but I disabled it and still wasnt working.
Think I need to download the latest version and install it and see what happens. Thanks to Windows updater.
I was also experiencing the same problem, but I read somewhere in the internet that if you are using skype you should open skype and follow the following path tool – options – advanced -connection panel and deselect the”use 80and 443 as alternative incoming connection” option. I did exactly that, now my browser is running but am getting this warnings:

What could be the problem?
