Hello Steve,
XAMPP has all that you need to do what you want in the one package (
except Joomla of course), but first an important step is to completely and cleanly uninstall XAMPP using the instructions found in the links below before proceeding to the next paragraph so you have a clean start - here perhaps is a complete easy to follow set of uninstall instructions in case you can't find them.
Make sure that all XAMPP components are
Stopped by using the XAMPP Control Panel and that there are no ticks in any of the
Svc check boxes.
Then click on the Exit button in the XAMPP Control Panel and save any of your own files that you may have in the htdocs folder, but
do not save any of the xampp files or folders as they will be reinstalled later.
Next delete the xampp folder completely - now proceed to the next paragraph steps.
It would now be prudent to uninstall the standalone Apache, MySQL and PHP instances so XAMPP can proceed to perform as expected without being concerned with conflicts that could be created by the other standalone components.
Please do make sure that they are uninstalled correctly and leave no residue on the PC or in the registry.
When you are satisfied that the uninstall went smoothly then you can go ahead and install XAMPP as outlined on the Apache Friends XAMPP for Windows home page.
