I created a new ASPX project and used the NuGet package manager to add EO.Web version 23.05.51. I added my licence to Global.asax. I added a new page and dragged the EO Slider control from the Toolbox.
I get this error
Click for Screen capture image

The text in red is shown immediately, and the Alert message is shown when I right-click.

The project is a Web Forms project in Visual Studio 2019

Thanks - but it now says my licence is not valid for this build

in Design mode:
I drag a "slider" control - I see a blue box saying "no style settings"
I right click and select "Edit Slider" from the list
I click "Yes" to "appearance settings ... built in template
I select Style 3 and click OK
I set the Width property to 400px
The blue box is now grey but still says "no style settings"
When i run the project I get
Horizontal Slider 'Slider1's Track.ImageUrl is invalid. It must be set.

I had understood the track image should be set to the default autoatically
