Vision Command and Exploration Mars software for Mindstorms RIS 2.0 I recently bought a set 3804 LEGO Mindstorms RIS (Robotics Invention System) v2.0 very well maintained but did not have the installation CD of the RCX program and IR tower. With some research on the Net, I managed to find the RIS v2.0 software and the expansions Extreme Creatures and RoboSports.

This set also includes the USB Camera from the Vision Command expansion but without the installation CD and the problem is that I can not find the software nowhere. Where can I download the software in English for the 9731 Vision Command and 9736 Exploration Mars??

I found a similar question here which was answered by another user with the links for the download of the software Vision Command but one was in German the other in French.
As it just so happens, I'm physically in possession of an English Vision Command CD. I've uploaded the iso here:

I didn't upload and post it in that other question you mentioned since I wasn't aware none of the Vision Command ones were English, but I've also updated the answer in that other question with this link for completeness.

Note that this software was originally designed for Windows 98. The very first thing you should do is run the install file in compatibility mode for Windows 98, otherwise you'll get an error telling you that your version of Windows is too new. And if you keep getting warning messages saying that this software has known compatibility issues, click "Continue anyway" for every one of them. I'm also wanting to say that you sometimes get an error when the camera itself is installing. In this event, just keep clicking "ignore" or "retry" or whatever until it finishes. I've been able to get the software to install and run on Windows XP, Vista, and 7, although the camera won't be recognized by your computer if your operating system is 64-bit. I'd be interested in seeing if that driver David Lencher linked you to would fix this problem for 64-bit operating systems.
