Solving the Xamp issue MySQL Service Detected With Wrong Path

I was trying to install on my 64-bit windows 8 machine, but i was getting continuously the following error,

 [mysql] MySQL Service Detected With Wrong Path
[mysql] Uninstall the service manually first
[filezilla] FileZilla Service Detected With wrong Path
[filezilla] Uninstall the service manually first

So I adapted the following solution after many other solution like restarting my computer, installing xammp again, running it with an administrator mode etc

But in actual following was the solution

1. Go to cmd and run it with Administrator mode.

2. Uninstall mysql service through command prompt using the following command.

                    sc delete mysql

When the installation is successful, run the xampp with administrator mode and install mySql to xampp interface and congrats your problem is resolved
