Verify game files, clear the download cache, repair the library folder, and switch download region: Steam's own fixes, in the order to try them.

Before you delete and re-download a 60 GB game, work through Steam's built-in repair tools. Most crash-on-launch and stuck-download problems are fixed by the first two.

1. Restart Steam and your PC

It sounds obvious, but a restart releases locked files and clears temporary state. Fully quit Steam (Steam > Exit), then restart the PC.

2. Verify integrity of game files (game crashes or won't start)

  1. Open your Steam Library.
  2. Right-click the game and choose Properties.
  3. Select Installed Files, then Verify integrity of game files.
  4. Wait for it to finish; Steam re-downloads anything missing or corrupted.

Seeing "1 file failed to verify"? That's usually a local config file Steam deliberately doesn't replace, and it's generally safe to ignore. Verify one game at a time, and not during a virus scan.

3. Clear the download cache (downloads stuck or updates failing)

Go to Steam > Settings > Downloads > Clear Cache (on Mac: Steam > Preferences), then confirm. Steam restarts and you'll need to sign in again. Your installed games stay installed.

4. Repair the library folder

Go to Steam > Settings > Storage, open the "…" menu for the drive, and choose Repair Folder. This resets folder permissions, which can stop updates from installing.

5. Change download region

In Steam > Settings > Downloads > Download Region, temporarily choose a nearby region. A different set of content servers often unsticks a slow download.

Important: don't uninstall Steam to "fix" it. Uninstalling Steam deletes your installed games. If you must, reinstall Steam into the same folder over the top of the old install, which keeps your games.
