hi guys
so is there’s a way to reinstall UE4 without downloading it again ?
Click “Verify” in engine installation menu, this will check integrity and download things that missing or corrupted (not sure about 2nd), delete files that you think they buggy and also click “verify”. If you delete Intermediate nad Saved directories in engine it will practically turn UE4 to frash installation if oyu want that, or else you modified other files.
