How to install app inventor onto Samsung intercept?

I am trying to install app inventor on my Samsung intercept. I have gone through the steps in the set up computer and phone. When it was ti开发者_C百科me to plug in the USB connection the two notifications did not display. Please, if anyone knows of any additional steps I need to take I would appreciate some advise.

Will is correct, i too have an intercept and it does not connect to app inventor. I believe it is something to do with the fact that there is no driver for windows 7 for the intercept. A driver separate from the mass storage drive driver.
