Designer Launcher does not launch!

Hi Specialists,

First of all, sorry if there is such topic already, but I did not manage to find it. My problem is that when I am trying to start the “Designer Launcher “, it does not come up. It does not appear in “Task Manager” at all. I power cycled my computer, I reinstalled the Java 64bit, I reinstalled and the “Designer Launcher” as well. Unfortunately, it still does not launch. The gateway is working and when I write http://localhost:8088/ it appears ant it is green.

If somebody have seen such thing before please help because I have a project assigned and I even can not start doing it.

I found that in Designer log file:
INFO [DesignerLauncher ] [2020/12/13 12:40:07]: Set initial logging level to INFO
INFO [DesignerLauncher ] [2020/12/13 12:40:07]: Updating logging level to INFO

You have this tagged as ignition 7.9 and 8.0. Which is it? The answers may vary depending on version.

I am so sorry. It is 8.
