Samanthi, in their own not-so-subtle way, people are saying that we're here to help thinking people, but we're not here to do people's thinking for them. After all, we don't get paid to do this, and some people would be so cynical as to say that when you come in asking such basic questions are these that maybe you're not really well-enough trained to be doing this kind of work. It's unfortunate, but there's a perception that any child can develop professional-grade software, and so some companies figure that they can just hire the cheapest person that comes along regardles of skills or talent. We know better and it causes resentment.

You can set the ANT_HOME and PATH environment settings permanently using the Windows Control Panel. And, no, I'm not supplying further help. The rest is up to you.
Customer surveys are for companies who didn't pay proper attention to begin with.
