Hello there ksmire. Did you find a solution to this problem. Could you please tell me what it was. I've had this issue for a while and needless to say it is extremely annoying. More or else exactly the same setup as yours (c folder, it was working before upgrade, etc).
I also have installed a variety of simulators, but only 3 show up in the debugging configuration window. Does anyone know how eclipse detects them?
Thank you
