Can't uninstall ASP.NET on Windows Server 2012

Question

Running aspnet_regiis -i on Windows Server 2012 doesn't work, so I need to uninstall/reinstall ASP.NET 4.5. However, I don't seem to be able to do so because the options are greyed out in the "Add Roles and Features Wizard". How can I uninstall ASP.NET 4.5 and re-install?

Answer 1

For Windows Server 2012 R2

1. Server Manger
2. Manage
3. Remove Roles and Features

This will bring up the Uninstall-only version of the GUI in your screenshot.
