Hi مساعد,
I am John J.D., a fellow Microsoft user like you.
I understand that you're experiencing an error with the Epic Games Launcher while updating it.
It's important to confirm the exact error message, so could you please provide me with a screenshot of the error?
I'd like to investigate further to provide you with accurate assistance. I tried searching for the error code "EOS ERR 1602" on the Epic Games support page, but couldn't find any specific information.
Thank you for your cooperation, and I'll do my best to help you resolve this issue.
Let's work together to resolve the issue.
Best regards,
John J.D.
