An accepted answer is supposed to be the one that worked for you.
If something did not work, or you cannot possibly see if it works for whatever reasons then that answer should not be accepted.
Even though accept rates do matter, they are not something that should cause you to start accepting answers just because those answers are highly upvoted.
Highly upvoted answers reflect what the community thinks should be the solution, not what actually is/will be the solution in your specific case.
