Wing FTP Software

dear sir,my boss's lab is based on offline,he asked me to build a ftp server,does wftpserver lincese must be on on line when server register？

您好，我导师的实验室的计算机环境是脱离互联网的内网环境，请问在我购买wftpserver的许可后，在注册时，是否需要必须联网？

Yes, after purchasing a license, you will receive a license key, you can register it under "Administration > Server > License" without internet.
