This error comes up every time that I open Horizon

This appears every time I open Horizon. Before this it wasn’t loading up then I uninstalled it and then removed all of the previous files then I installed it back and this had happened. I have done this 3 times again since then and this has always happened.

Can you post in text what the error message says?

'Unhandled exception has occurred in your application. If you click Continue, the application will ignore this error and attempt to continue. If you click Quick, the application will close immediately.

Visual Styles-related operation resulted in an error because no visual style is currently active.’

You can’t press either and you mus ALT-F4.

It it being caused by the theme you’re using. Switch window themes and there shouldn’t be any issues.

How do you change that?
