If you have already installed XAMPP on your computer, you can start it without going through the setup process again. Here are the steps to start XAMPP without setup:
Locate the XAMPP folder on your computer. By default, this folder is located in the C:\xampp directory on Windows, or the /Applications/XAMPP directory on Mac.
Open the XAMPP folder and find the xampp-control.exe (Windows) or manager-osx (Mac) file.
Double-click the xampp-control.exe or manager-osx file to launch the XAMPP Control Panel.
In the XAMPP Control Panel, you will see a list of services such as Apache, MySQL, and others. Click the "Start" button next to each service you want to start.
Wait for the services to start. Once they are started, you will see a green "Running" status next to each service.
You can now access the services such as Apache and MySQL from your web browser or other applications.
Congratulations! You have now started XAMPP without going through the setup process. You can use the XAMPP Control Panel to start and stop the services as needed.
