[Closed] Error R-1603
I've been trying to get this installer working for days, to no avail. I run it as an admin, I even installed Visual Studio.
I've installed every update I could for Windows 7, except for the Telemetry/Windows 10 ones (which I hid). If even those are required to be able to use this program, that would be ridiculous.

With the release of the latest Epic Games Launcher, comes a new workaround for this issue. NOTE: This workaround only applies to issues with the launcher prerequisites installer(LauncherPrereqSetup_x86.exe or LauncherPrereqSetup_x64.exe). If you are having problems installing prerequisites for engines or other products, this is not the thread for you.
As others have already noted, this is a rather common problem that people seem to be encountering. I've experienced it myself, as well. There's a couple things to check and do if you're running into this issue, as outlined below:
It is likely that following these will solve this problem, as illustrated by others already. If you still have trouble, reach out to Epic

I fixed it for my system. I don't know how this happened, on a fresh install of Windows 10 no less, but somehow my permissions were completely screwed.
Here is the steps I used to have everything install correctly without anymore 1603 errors or DirectX fails:
Open My Computer and right click on the system drive (C: in my case, even though I was installing it to D:), click on Properties.
Click on the Security tab, and then click on Advanced. Ensure the SYSTEM user is there and that it has Full Permissions (mine did, so I didn't think anything was wrong).
Even if it already has Full Permissions, click on "Change Permissions" on the bottom with the UAV shield icon on it.
On the bottom of this screen, after ensuring SYSTEM has full permissions, check the box at the bottom that says "Replace all child object permission entries with inheritable permission entries from this object."
Click Apply and it might ask you to once again grant it permission and then it will go through all files and folders on your system drive and re-apply those permissions.
It will throw errors about the pagefile and other things saying it can't modify those, which is fine. Those are all files that are currently in use by the system and don't want to touch those anyway.
After it completes, or during it may say the Recycle Bin has become corrupted and you will need to empty it. Go ahead and click OK and everything should be good to go.
Like I said, there isn't any reason a fresh install of Windows shouldn't have the System account have full access to everything. It's really weird. Hopefully the admins here can add this to their toolkit to help with people experiencing these weird errors.
