We are still working to resolve this issue and greatly appreciate your continued patience.
Initial findings indicate that corrupted game files may cause the update issue. Steps to perform a Repair Installation have been clarified below. Please ensure that the Repair Installation has completed fully before attempting to update the game version.
Added additional steps below to End Task on all open MapleStory, Nexon Launcher and BlackCipher programs running.
The MapleStory team is currently investigating an issue that prevents some users from updating the MapleStory client due to error message: "This product cannot be installed."
If you encounter this error, open Task Manager and End Task for MapleStory, Nexon Launcher and BlackCipher.
- Press Ctrl + Alt + Del to open Task Manager.
- Navigate to Processes tab and review list of open programs.
- For all MapleStory, Nexon and BlackCipher.exe programs, right-click program and select End Process Tree.
- Re-open Nexon Launcher and attempt to open MapleStory again.
If that does not resolve the issue, please perform a Repair Installation.
- Open up your Nexon Launcher.
- Click on the game page and click on the "gear" icon to open up your Game Settings.
- Click on "Game Configure" in the sidebar of the Nexon Launcher Settings.
- Select the game.
- Click on the "Repair Installation" button. When you click on Repair Installation you will receive a message that will ask if you wish to continue. Click 'OK'.
- Once you click OK, the repair installation will begin running and will verify the files within the game folder and check for any missing or damaged files. If it finds any, it will download those files and/or update them. Once it is complete the normal play button will return and you may launch the game normally.
To prevent other programs from interfering with the update process, please close all non-critical programs while the update is underway. We also recommend performing a Clean Boot to ensure other programs are not launched automatically.
If you are still experiencing this issue after performing the above steps, please submit a ticket with the following information:
- Create ticket with title: Nexon Launcher Issue - This product cannot be installed
