Exactly what the crafty older person wanted. Get you to do the work. "It doesn't work on my computer" or some other claim of trouble or ignorance is an easy way to trick a smart energetic young person to do something for you.
Young smart people don't like to say "I don't know how" or "I can't get it to work." An older person will say that without hesitation if it will prompt someone else to do something that he doesn't want to do himself.
For many people, the notion of debugging a MySQL installation on Windows so that it works seems about as plausible as summitting K2 - they don't expect others nearby can simply do it, either. (Also, the suggestion of inter-generational manipulation is not attractive.)
It’s kind of like the well known technique: “If you want the right answer to your question, confidently post the wrong answer and wait for the replies.”
Agreed.
The charitable interpretation is a lot more reasonable: a parent/elder wants to spend time with their child/younger, and is even taking an interest in their career/hobbies.
As an aside, commonplace implicatures like these are a kind of what's called "pragmatics" in linguistics.
"want"?
