Have already installed a Samsung USB drivers and update it as well.
Do not forget to also enable USB debugging mode on Android of your phone.
Disable Samsung KIES and antivirus temporarily so they won't mess the flashing process.
For a rooted Samsung Galaxy Alpha, then I must tell you that your root access will be wiped out for installing this official update.
A stock recovery image will replace your existing custom recovery (If you have that kind of recovery).
Make sure you battery life is sufficient to perform this action.
