When a game is downloaded from PlayStation Store or a PS4 game disc is inserted into the system, the game automatically begins installing. Some games allow you to launch them early to start playing as they continue installing in the background. If you receive this error while playing, it means the game has not fully installed yet. Please do the following to check the download status of the game:
When on the PlayStation 4 home screen
→ Select the game
→ Press the OPTIONS button
→ Download status
We recommend waiting until the game is fully installed before launching it again. If the game appears as “Installed” and you are still getting the error, try deleting the installation, then reinsert the disc and reinstall the game fully before launching.
