Tooling: Can't start .net core 1.1.0 project, seen similar issues

[frksn]

I create a default empty project, with .net core 1.0.1, it runs fine. I upgrade to 1.1.0, it fails to start. I revert to 1.0.1, it works fine again. Visual Studio Enterprise, initially update 3, then uninstalled, reinstalled with update 2.

The program '[22664] dotnet.exe' has exited with code -2147450749 (0x80008083).
The program '[20320] iisexpress.exe: Program Trace' has exited with code 0 (0x0).
The program '[20320] iisexpress.exe' has exited with code 0 (0x0).

The event log:
Failed to start process with commandline '"C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\IDE\Extensions\Microsoft\Web Tools\ProjectSystem\VSIISExeLauncher.exe" -debug -p "C:\Program Files\dotnet\dotnet.exe" -a "f:\xxxxx\WebApplication2\src\WebApplication1\bin\Debug\netcoreapp1.1\WebApplication1.dll" -pidFile "C:\Users\xxxxxx\AppData\Local\Temp\tmpEE80.tmp" -wd "f:\xxxxxxx\WebApplication2\src\WebApplication1"', ErrorCode = '0x80004005'.

I found similar issues, but none of the tips helped till now:
https://github.com/aspnet/Tooling/issues/682 --> my vs is english
https://github.com/aspnet/Home/issues/1719 --> same behavior, but different error code
https://github.com/aspnet/Tooling/issues/730 --> the folder mentioned in this issue exists.

Thanks for any information that can help me fix the problem.

1.1 installed on the machine? Select "Current" at https://www.microsoft.com/net/download/core to get 1.1.

It was the runtime. Bad version. Didn't cross my mind to check this one. Thank you.
