The warning message informs you that the business card scanner driver has not certified by Microsoft (we have submitted it to Microsoft for certification, but it will take some time to go through the process). In case of Windows XP OS, click "Continue Anyway" to install WorldCard Ultra driver. If you are using Windows Vista OS, the message will be “Windows can't verify the publisher of this driver software”. Click “Install this driver software anyway” to continue.

Please feel relieved, it will only install WorldCard Ultra driver, will not harm your computer or steal any information. Again, we have submitted it to Microsoft for certification, but it will take some time to go through the process.
