RunUAT.bat Error Unreal engine 4.8 Preview2

I want to thank you for your reply, i didn’t think a staff would be caring enough to read through a bunch of stuff just to help out, so thank you.
however I have tryed to package this back on the previouse version 4.7.5 on the windows, and still not able to package, runuat.bat error. Any other solution/suggestions?
