here is the problem.
I've installed Xampp 1.7.3 but some day ago, MySql seems doesnt want start.
I tried to uninstall and reinstall but nothing to do.
In Xampp control panel I tried also to uncheck flag to SVC about mySQL (uninstall) and press Start..
In this case too doesnt work
If is installed like service, when I go to service management and I press "Start" , answer is
"Error 1067. Unable to start service Mysql"
Firewall is disabled
Php running without problem
OS is Windows XP SP3
