Hey

Please try the following: Go to where ever the Engine is installed to, for example: Epic Games\4.7\Engine\Binaries\Win64 and locate ‘UE4Editor.exe’ Double click on the editor to open it. Let me know if just opening the .exe gives you an error or not.

If opening the .exe file does not work for you, please try verifying your engine within the Launcher. You can do this by opening the Unreal Launcher, click on ‘Library’ and then press the down-arrow that’s under the most recent version of the Engine. Once you’ve gotten to that point, click on ‘verify’ and UE4 will then verify that version of the engine. Please make sure that you are working out of the most recent version of the engine which is 4.7.2.

**Troubleshooting the Launcher:**

If none of the above corrects the issue you’re experiencing, please reply back to this thread. Please include as many details as possible regarding your issue.

Thank you.
