Hi there,
Sunday night I left my computer downloading UE4 from the Epic Games launcher and when i woke up this morning, it was showing that the installation process failed, with error code E-1223. I tried downloading 4.10.4 with plenty of spare space (13 GB or so) with my computer charging and everything. I saw a post on this before but i’m afraid i’m not used to windows computers ( im using an asus notebook ) and I had absolutely no idea how to do anything that would help the situation, such as uninstalling various things i cant even find in the finder. I only know how to operate UE4 and not download it, as i only did a course on it at camp. I have virtually no experience with windows computers.
If someone could baby-step me through how to help this that’d be great.
