VS2017 is installed, but the 'Blank Solution' templates do not appear. I tried uninstalling and reinstalling without success. Has anyone ever been in this situation?
You need to install by the Visual Studio installer.
Clickthe"Workload" tab in the upper left corner, then check the ".NET-Desktop Development" right corner and click Install. Note that this can change the size of your installation (bottom right corner), and you can install other Workloads, but you must install at least ".NET-Desktop Development".

Installedfolder:"C: \ Program Files (x86) \ Microsoft Visual Studio 14.0 \ Common7 \ IDE \ ProjectTemplates"
Custom Folder: "C: \ Users \ Documents \ Visual Studio 2017 \ Templates \ ProjectTemplates"
