xampp MySQL does not start

You have two versions of mysql using the same port 3306. Change the port by:

1. Stop the xampp server, if it is already running.
2. Edit the value to "port" in xampp/mysql/bin/my.ini

Here:

# The following options will be passed to all MySQL clients
[client]
Password = your_password   
port =  3306  #--->  3307  
socket =  "/ xampp / mysql / mysql.sock"

and also here:

The MySQL server 
[ mysqld ] 
port =  3306  #--->  3307 
socket =  "/ xampp / mysql / mysql.sock"
2. Start mysql service

I found out that re-installing Xampp as an administrator and running it as an Administrator worked.

You already have a version of mySQL installed on this machine that is using port 3306. Go into the most recent my.ini file and change the port to 3307. Restart the mySQL service and see if it comes up.

You also need to change port 3306 to 3307 in xampp\php\php.ini
