I could upload you the free 90-day trial version of the ZEN software, but it is about 6 megabytes, and the forum only allows 300 kbytes for uploads. I could E-mail it to you. You can send a private message with your Email to me if you want.
Don't forget, you will need a special cable to communicate with the ZEN. The cable and software are not expensive. You may want to contact your local Omron distributor.
