Error IS-EO-Lnc-BldInfo:Http-403

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
