VNC Pass View is a totally free, tiny utility that requires no installation and lets you recover the password stored in the VNC program.
In reality, VNC Pass View lets you recover two types of password: the password for the user to identify themselves (meaning the HKEY_CURRENT_USER information of the Registry) and all those passwords stored for all users.
For VNC Pass View to work correctly you don`t need any additional DLL. The program author`s website has many different language translation modules.
