No, Sorry about posting twice, first post disappeared first time around, its just same picture, I just reposted it and edited out name of computer account, I only just found out that both images came through.
So back to problem. I have only 1 user account on computer and launcher just will not start. I double click launcher or right click and press Open, it will process for a fraction of a second and then nothing happens. So in fact launcher never started at all. UE4 does nothing. And I would really like to start learning it real soon.
