Well i downloaded the newest version, then installed, checked to instal entire files on local drive. I restarted Visual Studio 2017 Community and rerun it. Unfortunatelly i can't find in menu > tools anything with should be connected with stylecop ( as in tutorial "how to use stylecop"). I am using x64 Windows7. I really really don't know how to to use it.
Go to extensions and updates and search for stylecop in the online area.
Choose the one by Chris Dahlberg.
Close VS and it will install.
open your project up and make sure you have a settings.stylecop file in there.
right click on the project in the solution explorer and you will see a run stylecop option
