Hey halfmoon_games,
How did you uninstall the Launcher?
Try doing this again through the ‘Remove Programs’ options within Windows. On a Mac you can simply drag the application to the trash bin.
Then navigate to where your ‘VaultCache’ is located for the Epic Games Launcher. You can find the directions for locating this folder on our Launcher Troubleshooting Guide below.

Delete this folder, restart your computer, and do a clean re-install. Hopefully this resolves your issue, but let me know if you are still in need of help.
Thank you,
