Ok so, I was attempting to download Fortnite earlier (I know it’s not specs because I’ve downloaded it before) and after opening, I got an error message saying “Epic Games Launcher is already running, exit to continue.” It had the option to ignore, retry, or exit. I tried all three and when I chose exit it shut the launcher, retry gave me the message repeatedly, and ignore made it look like it was loading then it said the launcher had ended prematurely. I have no clue what to do I’ve tried 3 times.
Reinstall launcher and restart computer?
