Quick answer: If CE-100045-0 appears after a game update, restart the PS5, make sure there is free storage, restore licenses, and try deleting and reinstalling only the affected game. Use Safe Mode Clear Cache/Rebuild Database before considering any console reset.
Before you start
- The correct PSN account for the game
- A stable connection and enough free storage for a full reinstall
- Cloud or USB backups before any reset step
Steps to fix the error
- Restart the PS5. Close the game, restart the console, and retry the update once.
- Check free space and the download queue. Cancel a stuck update, remove unneeded downloads, and leave enough room for the game plus update working space.
- Restore licenses. Go to Settings > Users and Accounts > Other > Restore Licenses. This refreshes entitlement records but does not remove saved data.
- Delete and reinstall the affected game. If the game can be deleted, remove only that title and download a clean copy from the Library. Back up local saves first if they are not synced.
- Clear cache and rebuild the database. Start PS5 in Safe Mode, choose Clear Cache and Rebuild Database, and try Clear System Software Cache first; use Rebuild Database if the icon or storage index remains stuck.
- Stop before Reset PS5. Reset PS5 and Reset PS5 (Reinstall System Software) delete user data. Use them only after PlayStation Support recommends them and after a verified backup.
Why this works
The error often appears when an update, game installation, license record, or storage index becomes inconsistent. Restarting, refreshing licenses, reinstalling one game, and rebuilding the database target those layers without wiping the console.
Safe alternatives
- Sign out of PSN, restart, and sign back in once.
- Update PS5 system software before reinstalling the game.
Warnings and limitations
The source video treats console initialization as a worst-case option. PlayStation confirms that Reset PS5 deletes all user data and Reinstall System Software also removes the system software. Those are not routine fixes.
Frequently asked questions
Does Restore Licenses delete anything?
No. It refreshes the account’s content licenses.
Will deleting a game delete its save?
Game data and saved data are managed separately, but back up saves before troubleshooting.
Which Safe Mode option should I try first?
Clear System Software Cache, then Rebuild Database if the problem persists.
