Asp.net core dotnet.exe error -2147450749 (0x80008083)

I've a problem with the new visual studio 2017 and asp.net core. When i create a new asp.net core project I receive this error in console when I launch the application.

Il programma '[8004] dotnet.exe' è terminato con il codice -2147450749 (0x80008083).
Il programma '[2288] iexplore.exe' è terminato con il codice -1 (0xffffffff).
Il programma '[8100] iisexpress.exe' è terminato con il codice 0 (0x0).

I don't have any idea, I've installed all net core platform and version but it is not working.

Stefano - Visual Studio is 32 bit only (there is no 64bit version) so in order to keep the bit depth the same - things that work with Visual Studio must be 32bit.
