Using Password Keeper is easy.  Download either the free or professional version of Password Keeper, and the simple installation program will have you up and running in no time.  

If you are upgrading from the Free version of Password Keeper to the Professional version, just run the installation for Password Keeper Professional, and it will load over the top of your Free version, retaining all your password information (of course).

Once installed you can begin using Password Keeper immediately regardless of the version you chose.  To use the additional features in the Professional Version you will need to purchase the unlock codes for Password Keeper Pro (registration process).  Your unlock codes arrive in your email box within the hour after purchasing Password Keeper Pro (by most purchasing methods).  Even before you received your unlock codes you will not have to wait to begin using Password Keeper just as you always have.
