Unreal Engine 4 Epic Games Launcher not starting

Hi, I’ve followed instructions in troubleshooting, WIN: “C:\Users"Username”\AppData\Local\EpicGamesLauncher\Saved\Logs"
My computer is a windows 7 professional. It has lead me to two EpicGamesLauncher text Documents but their size is 0 KB and when opened are empty.

Also tried uploading EpicGamesLauncher txt files at end of;
“C:\Users"Username”\AppData\Local\EpicGamesLauncher\Saved\Logs"
But when I hit okay, it says file is too small to be uploaded.
Hitting Alt&Tab reveals that Epic Games launcher is not running however Task Manager tells me it is.
