Unreal Engine 4.10 update repeatedly failing

Trying to figure out what the deal is with this today. It’s been like this for a week. I try to update, it takes hours to download the update, then says it has failed with error code “E-1223.” The troubleshooting guide currently says:

The necessary prerequisites have failed to install. Error Code 23.

If the Epic Games Launcher fails to install the Unreal Engine 4 and it provides this error message, please see the following:

  • For UE 4.10 and above, Visual Studio 2015 redistributable components are required for the editor to run. UE4 includes Microsoft’s standalone installer which attempts to install these, but this can fail if your Windows Update is disabled or if your version of Windows is not updated to the latest patch. To resolve this issue, please run Windows Update.

but I have done all that. My Windows 10 is completely up to date, and I have the most current Visual Studio 2015 redistributables, both x86 and 64, installed direct from Microsoft. I think I will try uninstalling them, and then running the update again, as suggested in this forum – if it really is trying to install them, maybe it is failing because mine are actually newer.

A troubling thing is that, after the installation fails, the download doesn’t stay on my drive. When I try to run the update again, it needs to spend hours tying up my internet for hours downloading another 3 GB, for no apparent reason. If anyone knows the proper solution to this, I’d appreciate hearing of it.
