Can't install/uninstall UE

I had Fortnite downloaded on a “G” drive when the drive crashed on me while gaming…

It kept telling me invalid drive so I went and allocated a smaller “G” drive to re-install it… The install will initiate and say that a epicinstaller-7.4.0.msi or something like that cannot be located and browse to path it to it…

I’ve tried using Revo Uninstaller nothing left on there I can find to uninstall I’m really losing hope for UE and Fortnite.

I also tried using windows tools to no avail anything related to UE doesn’t show on the list.
