--- Comment #7 from marc.rainier.lopez@gmail.com --- I'll let you know. After attempting to run my iTunes copy in Wine 10.17 without success, I reverted to Wine 10.14 and it works again.
My plan is to get commit d62035da4aa91327c6e38a2c8a66b829eb0983ed and then apply the patch you provided. Will give logs if it still doesn't work.
