Hi hex 198,

Windows Service Pack 1 is required to install and run the Launcher and UE4. There is no way to bypass this. You must have those updates unless upgrading to Windows 8 is an option for you.



@TJ Ballard I was able to Install UE4 (epic games Launcher) Just By Troubleshoot Compatibility…
Maybe To Run Launcher I do need Win7 SP1
by The way thanks For Reply
