Why isn’t MapleStory Opening?

To improve game performance and support future development, the MapleStory game client has been upgraded to 64-bit and no longer supports 32-bit systems.

This means that MapleStory will not open on PCs running a 32-bit operating system.

If MapleStory is not opening for you, check your PC’s system information before troubleshooting (see Finding your system type).

If you have a 32-bit operating system, switch to a PC running a 64-bit operating system to continue playing MapleStory. If you already have a 64-bit system, refer to the Troubleshooting section below.

For more information about the upgrade, see the following Maple News articles:

• MapleStory Updating to 64-bit Client with v.231
