I also have a problem with Cura 4.7.1, Windows 64 bit version.
I've been running 4.6.1 sucessfully and saw the invitation to upgrade so did. The install process worked.
But starting Cura doesn't. I get to the window asking for me to contribute by sending anonymous data and click on 'Next'
Cura silently closes. No error messages, nothing.
The same multiple times, even after a restart.
Has anyone tried this with W10? It seems pretty solid and as I've not even got to the point of selecting a printer seems pretty generic.
Will return to 6.7
