MapleStory installed without any problems.
What does not
When the program was started it hung when trying to download the Gecko drivers/Mozilla. I had previously downloaded firefox for windows and installed it with wine.
If I selected to not install the gecko engine the title screen started with an indication that html rendering was not functioning.
The program failed to load any further.
