During internal testing for v159, we discovered an issue with the auto-patcher and the manual patcher that would affect many players on v158.1 or v158.2. Players who already exclusively use Steam or Nexon Launcher to play MapleStory will not be affected by this issue, so they can disregard the following.
If you encounter "Map.wz is corrupt" error while using the auto-patcher or the patching stops on the map.wz file while using the manual patcher, please follow the steps below to get the correct files for v159.
[Update 1/21 11 PM] We've updated the v158 to v159 auto-patcher and the v158 to v159 manual patcher. While this will address the patching issues for more players, there will still be some players who are affected. If you are experiencing issues patching from v158 to v159, follow the steps below.
Simplest method
Click here to download the v159 full client downloader.
Run the
MapleStory_Downloader.exe when it finishes downloading and follow the prompts to install the client.
Here's what the downloader will look like when it's running:

If you already have MapleStory installed in the folder you chose, a warning message will appear letting you know that the current folder will be deleted and replaced.
This includes your screenshot folder if you keep your MapleStory screenshots here, so be sure to move your screenshots out of this folder if you want to keep them. When you're ready to do this, click "OK."
