hi ,
You must right click The EP Launcher in administrator. The official answer
IS-INFO-DSTCVPAT error appears when trying to update a game - Epic Games Store Support
This was a known problem a long time ago and is still valid
MUST right Click “RUN AS ADMINISTRATOR” on uninstall/install
Plus my thread was here
UEFN will not install correctly from Launcher on any Windows 11 (eleven) version needs to run Elevated "Run As Administrator - General / Issues and Bug Reporting - Epic Developer Community Forums
If neither of these work
Restart PC
Log in as Aministrator
Uninstall using Windows 11 Uninstall to remove Epic Games Launcher UEFN and Fortnite Creative
