A question not having an answer, unless it's a really bad question or a really localized question (this doesn't seem to be either), isn't a sign that the question shouldn't exist: Closing or deleting is not ideal, as others might have the same issue and would benefit from seeing at least what might work, even if the answers so far haven't been a complete solution to you.
Unless your accept rate is abysmal (like, less than 60%), don't worry about it.
So, you're really left with two ideal options:
If you found a solution to your problem, even if your final solution is based on the other answers provided, leave it as an answer and accept that: this way, people finding your question will know what worked for you and you'll save them some time.
If you haven't found a workable solution yet, update your question with what you've tried so far, and try to look at what you can do to address why the answers so far aren't what you're looking for. It looks like you did that in a comment on one of the answers: incorporate that back into your question.
If you really want to get a better answer and editing your question hasn't helped, consider offering a bounty, which might be the carrot a person needs to provide a good answer.
