Downloading Unreal Engine 4

I am unsure if this is the correct place to post this, but I seem to be unable to download UE4. I have tried several times over a period of months, but invariably I end up turning off my computer a few days after starting the download due to storms … And I’m still at 3%. All other downloads (such as Steam) work perfectly. Unreal does not. When downloading the launcher or launcher updates the download percentage wobbles back and forth, often dropping drastically (ex: 10%). I have tried solving this multiple times and multiple ways. I did eventually succeed in downloading the launcher (quite a while ago) and found I was utterly unable to download UE4 itself, as mentioned above. Help woukd be much appreciated.
