When I clicked the setup file of XAMPP, a warning showed saying User Account Control(UAC) restricts XAMPP... It also happened after I turned off Real-time Protection under Virus and Threat protection of Windows Security, and also after I set the slider of UAC settings to never notify. Also, I uninstalled Skype.
Real-time Protection turned off
UAC settings slider is set to never notify
During the first installation, a warning showed from Windows Firewall with checkboxes for private and public accesses. But it didn't show up during the next installations after I uninstalled XAMPP. I don't remember whether I checked the two boxes or not.
After installation, I run the XAMPP control panel. When I click Start for either Apache or MySQL, it is said that something is not found... and I click OK 4 times. And the XAMPP control panel shows Apache/MySQL shutdown unexpectedly.
File not found and Apache/MySQL shutdown...
I also tried changing 80 to 8080 in some files while watching some answers from this website but they didn't solve my problems.
How to solve the problems, and why the checkboxes for private and public networks don't come?
