If you can't flash Espruino, the problem is probably that the board you have uses a fake Prolific PL2303 chip for USB. Prolific got fed up with all the clones of their chip, and tweaked their drivers so that they don't support it.
Just type pl2303 windows 7 problem into google and you'll get a bunch of suggestions from people with similar problems.
Or... you could get one of the official boards, which 'just work', and help to pay for my work on improving and supporting Espruino :)
