Epic Games Launcher version 19.0.0 does not start on Core 2 Duo CPUs due to lack of SSE4.2 support.

Launcher version 19.0.0 requires SSE4.2, which is not supported by Core 2 Duo processors, currently listed as minimum compatible requirements:

Steps to reproduce:

Attempt to launch the Epic Games Launcher v.19.0.0 on a system with a Core 2 Duo CPU (or any other CPU without SSE4.2 support) running Windows 10 x64.

Expected vs. actual results:

Expected: The launcher opens; Actual: The launcher does not even open.

Relevant lines on EpicGamesLauncher.log file:

Message dialog closed, result: Ok, title: Message, text: This CPU does not support a required feature (SSE4.2).
LogWindows: FPlatformMisc::RequestExit(0, FWindowsPlatformMisc::PlatformPreInit.CPUNotSupported)
LogWindows: FPlatformMisc::RequestExitWithStatus(0, 0, FWindowsPlatformMisc::PlatformPreInit.CPUNotSupported)

Yea thats why i cant get it to open on my Dell precision 490. I hope the devs fix this

Same problem here with an Intel Xeon X5470 (similar to Core 2 Quad) with no SSE 4.2
I have been talking with support and I had no success. They recommend me to talk with my “technology provider” in order to “update” my computer… :face_without_mouth:

Support is useless in a case like this, they only can guide you to reinstall the launcher, restart the computer and tips like that.

We need an Epic dev to check this problem and release a new version or, at least, let us downgrade to v.18. If you find a v.18 installer it automatically installs v.19, we can’t go back to a working version.
