Original software downloads
Here is the link to download laserDRW and WinsealXP from the board vendor; 李辉宇的软件站-下载. As other have pointed out when trying to access the website, your browser will tell you it is not safe. I have browsed their site many times and have not gotten any cooties so far. There is a manual on how to use the software but it is in Chinese. As far as I can tell, it is the same software on the CDs and is not an update.
UPDATE downloads can also be found on the main page http://www.3wcad.com/ no virus warnings.
