Oh! Hi!
I'm sorry to announce that the new version of the IRO Renewal client that was released on is indefinitely incompatible with Wine/CrossOver because, like the Transcendence client, it incorporates Easy Anti-Cheat (EAC). Gravity have adopted EAC to prevent the use of bots and unauthorised client modifications. The European version of the client is also incompatible with Wine/CrossOver because it incorporates software similar to EAC.
As far as I'm aware, it's not possible to bypass EAC because it's highly sophisticated and is integrated with the Ragnarök Online server. Regardless, bypassing EAC would violate the IRO terms of service. Additionally, it's not possible to enhance Wine/CrossOver to enable EAC to run because EAC is specifically designed to detect Wine/CrossOver.
As it's currently impossible to run the International or European Ragnarök Online clients under Wine/CrossOver, and as IRO blocked access from Europe (where I live) in May 2018, I've decided to abandon (1) my guides for playing Ragnarök Online under Wine/CrossOver and (2) the development of the IRO custom installer. The guides will remain available as a reference, but they won't be updated.
It's unfortunate that Gravity chose the most inimical option to prevent the use of bots, but it also shouldn't be surprising to anyone who has experienced their treatment of their customers over the years since IRO launched. If you're unhappy about Gravity's decision to permanently preclude the playing of Ragnarök Online on Linux and macOS, then I encourage you to voice your opinion via the WarpPortal forum.
It was fun while it lasted.

Psst… Due to Brexit, this website will be moving to a new .uk domain in the near future. The following are the new locations of my Wine/CrossOver guides:
