It seems that you are missing an OCX file. That is the error message you encounter when the file is missing or it's not correctly registered.
To register it please open Start > Run and type regsvr32 C:\Windows\system32\CIFTP.OCX. If you receive a successful message that means the library has been correctly registered. In other case, the file is indeed missing and you will need to re-install it. Most probably, the file is installed from another package requirement. Please check your setup folder of the main application for additional packages.
