Trouble: can't launch UR4!

I have just finished downloading Unreal Engine 4 (4.25.1). It doesn’t launch at all.
I can’t seem to find a solution. No errors pop up whatsoever.

Here are my specs:

mocOS High Sierra v 10.13.4
Processor: 2.6 GHz Intel Core i5
Memory: 8 GB 1600 MHz DDR3
Graphics: Intel Iris 1536 MB

If you have any question to find a clue, please ask away!

Your computer does not meet the minimum requirements to run UE4
