You work through lots of the flowchart and eventually get stuck. Then you ring up Tech Support and you start from square one of the flowchart again.
Then if you start over at the beginning while on the line with them and figure out the answer yourself they will still want to charge you for the call. When that happened to me I tried to work a deal with the guy where I'd tell him my solution if he wouldn't charge me. He said he didn't have the power to make that kind of decision.
