except the Apache service does not start (MySQL and FileZilla are OKed). How do I fix that?
I don't know. I missing a correct error report from you...
For example, how do I upload a .html file so I can see how it work.
You know how to copy files with the explorer?
Same as MySQL
I don't know what you want to do with MySQL.
BTW: try phpMyAdmin and the MySQL manual
What's the problem with FileZilla? It's a ftp server. So you need a ftp client to use it.
And have a look at our Demopages at http://localhost/xampp/
