# Update Closes Unexpectedly * When the Launcher or a game update closes unexpectedly due to a network error or PC restart, you may have to reinstall the game. * If this problem occurs, the "Install" button will be displayed, and clicking it will begin the game's reinstallation process. You can run the game normally after reinstalling it. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
