Hello Pacsoft. The NI Vision Development Module is too big for most people to download off of the web. In fact, I believe it barely fits on a CD! However, you can request a 30 day evaluation by going to
www.ni.com/vision/vdm and clicking on the Request Evaluation Software link.
If you have questions about the tools or how to use them in your application, just post them to this forum.
