I don’t know if maybe my laptop isn’t powerful enough but everything dowloaded and installed but when I click launch, it looks like its about to load, then nothing happens.

I have a HP probook 4430s Intel(R) core™ i5-2430m CPU @ 2.40GHz (4 CPUs), ~2.4GHz 4G of Ram
Windows 7 pro 64-bit

Someone please help me!

Does your video card support Dx11?

Check out this thread: DX11 feature level 10.0 is required to run the engine. - Rendering - Epic Developer Community Forums

Could you post your Dxdiag (system specs)? Although you have Directx 11 installed, your graphics card may not support it. Also, there are other updates that we can see from this file.

  • Windows: Go to the Start menu and type ‘dxdiag’ into the search bar. Open that file and then click ‘Save All Information’. Post that text file here.

hi, I too have this problem.

Hi thomas1097, I’ve noticed you have the 4.8.0 preview build installed. It being a preview build, there are often bugs that come along with it.

One known bug is that you must have downloaded and launched a previous engine version(4.7.6 would work) before the 4.8.0 preview build will launch.

So try downloading 4.7.6 and opening it up. No need to create a new project or leave it open. Once it has been launched, 4.8.0 will launch every time after that. You can even uninstall 4.7.6 at that point if you wish.

Keep in mind, if you uninstall the Epic Games Launcher, you will likely have to go through this process again.

Hope this solves your problem.
