Installation and operation has been disastrous. Tried several times to install and run and continually get the Port 80/PID 4 error in Apache Control Panel. Have completely removed Skype from system and rebooted (cold start). Completely removed XAMPP and rebooted with essentially same message. Am not a Windows Tech and really don't want to fool around with changing things without exact instructions which do not seem to be provided in this forum. Below are screen shots/copied text from Control Panel. What to do?
Control Panel info:
XAMPP Control Panel v3.2.1
Red X for Apache, no PID or Port, Clicking Start regurgitates the 'error message': Apache shutdown unexpectedly, etc, etc.
Green Check for MySQO, no PID or Port
Red X for File Zilla
No Check for Mercury
Red X for Tomcat
