I am taking a course through Lynda.com, I was given instructions to download XAMMP from http://bw.org/ldcsql/. When I got to that site I was directed to a Lynda site which told me to download it from the page shown which for Win had XAMMP-win32-1.71-installer.exe. I was told it couldn't be verified but downloaded anyway. I chose "English" for the language and received a message " MS Vista: note because an activated windows Vista user account control on your sys, some functions of XAMMP are probably restricted. UAC avoid to install XAMMP to C/program files (x86) because of not enough write permission or deactivate UNC win msconfig of the setup." I am not running win vista so i figured it did not apply to me. Every thing extracted and installed. When I went to the control panel to open MYSQL it opened port 3306. When i tried to start Apache i get a busy message for port 80 "busy". I don't believe anything else in on port 80. I don't know how to check or correct it if I need to. I am new at this and trying to learn to develop web pages etc. I am not running a Skype program, and cant figure out how to rectify this.I have tried it several times deleting the previous download prior to downloading the new one. Lynda directed me to Microsoft who directed me to you. HELP PLEASE.
