I wonder if there is a virus scanner running that prevents the installer from loading correctly.

thats what i mean whit put it in a folder c: (your name). sometimes a file cant left behind whit remove cause another program use it to. so you can keep removing and installing,it will not work. i learn this trick from a programmer whit my earlier robot programs.

No this is my personal network and there aren't any restrictions in place. Though I do want to control my Roomba from school to do my chores eventually, when my WiFi board arrives. I think I'm going to take a look and see if there's something mucked up with my OS. Going to try running it on a different machine.

you have a network problem to open ARC?
