Windows says “Windows protected your PC”
Windows shows this for any new program it has not seen many times. Click More info, then Run anyway. Only download the game from deepworldonline.com.
My antivirus removed a file
Add the Deepworld folder to your antivirus exclusions, then open the launcher and press REPAIR FILES to restore anything that was quarantined.
The game won’t start or crashes
Open DeepworldLauncher.exe and press REPAIR FILES. It re-checks every game file against the official list and re-downloads anything damaged or changed. If it still fails, ask in the Discord.
I ran Deepworld.exe directly and nothing happened
The game must be started from the launcher. Start DeepworldLauncher.exe instead and press PLAY.
The download stopped or failed
- Keep the launcher window open until the download finishes. If you close it mid-download it deletes the partial files so the next run starts clean.
- If it shows an error, check your internet connection and press RETRY: partial files are kept and it carries on.
- “Can’t reach the update server” means the launcher could not check for updates. If the game is already installed you can still press PLAY.
Where should I put the folder?
Anywhere you like, for example C:\Deepworld, as long as the launcher sits in its own folder. You can move the whole folder later. If you run the launcher in a folder that already holds other files, it installs the game into a Deepworld subfolder instead, so your own files are never touched.
My extra files disappeared
The launcher removes files from its game folder that are not part of the official game. Keep mods, screenshots and other files somewhere else.
Still stuck?
Ask in the Deepworld Discord and tell us what the launcher says.
