Epic games launcher not launching 0xc0150004

[maks_the_beast]

My friend cant play fortnite with me as every time he launches epic he gets an error called the application was unable to start correctly (0xc0150004) click ok to close the application. He lives too far away from me and has windows in another language. It occurred as his pc turned of during a windows update. Then he had an error where it said restoring to previous windows when he bought his pc pre built with windows 10. Eventually there was this disk repair going on and he was back in but literally the only app that isnt working is epic games. We tried to run it in compatibility mode and other windows mode, reinstalling epic, and closing through task manager. Pleas help

Get him to try this

right click start button
choose powershell (admin)
type SFC /scannow and press enter
once its completed, copy/paste this command into same window:
Repair-WindowsImage -Online -RestoreHealth and press enter
SFC fixes system files, second command cleans image files, re run SFC if it failed to fix all files and restart PC
