Couldn't find platform name/Using Just My Code

Development Platform & Builds Mobile
, , , ,

Windows 7, VS2015
UE4.12.5 release
“Couldn’t find platform name” - red font in the console.
It happens when I am trying to first run UE.
I followed all instruction. I have just installed it.
It has been builded.

I also have VS2013 and VS2015 side-by-side. (Installed VS2015 firstly.)
What should I do to set Windows a target platform?
(button “run” instead of usual “attach”)

I also have error message:
You are debugging Release buil of AutomationToolLauncher.exe. Using Just My Code with Release builds using compiler optimizations results in a degraded debugging experience(e.g. breakpoints will not be hit)
Stop
Disable
Continue

Could you please describe this problem and possible solutions?

Had the same issue, turns out my startup project was set to UnrealBuildTool. Once I changed it to the name of my game’s project, it all worked fine for me.
