You need to clear your Port 80 issue.
In many cases this port would be blocked by a Windows service called world-wide-web publishing (or WWW-publishing) or a part of the IIS Webserver component.
So try to find and stop that windows service and/or uninstall IIS in the windows components dialog, if you don't need it.
second thing: why is MySQL started from C:\apache\ and your XAMPP install path is C:\xampp\? Have you moved something?
Maybe it is needed to execute the setup_xampp.bat file again to change the paths of the components to the current path.

That would in no way effect any blocked ports, so how should that solve that issue?
