MySql installation

I first i had installed MySql 4.1 in my computer ..

Unfortunately, there is an error occur where the MySql service cannot start and come out with an error message "error 1067".. trying uninstall and install again for many many times .. But the problem still cannot resolve. So, i tried the steps below:

1) uninstalling all the MySql services and using the add and remove in control panel.
2) delete all files that had previously created by MySql
3) check the register files and see if there is still something installed in the system.
4) stop and remove the installed MySql service.
5) reinstall again .. and then IT works ..

gosh .

p.s. Don't set the password for the root user.

Finally .... its alive
