I have installed the suite of controls for winforms, but I can't get them to appear in the toolbox. When I use Extension / Telerik / Telerik UI for Winforms / Launch Toolbar configurator it shows me the control options and is supposed to add them to the Toolbox, but they don't appear. If I select the Show All option then all the Telerik control categories appear, but none are enabled. So I did it manually and it remains the same.
This image shows the toolbox after using the Telerik extension Launch toolbox configurator
As you can see, no tab appears with the Telerik controls.
And if I tell it to show me all the tabs, the Telerik controls do appear, but they are not enabled, as can be seen in the following image:

Hi Javier,
The screenshot suggests that you are having a .NET Core, .NET 5 or NET 6 project. In such projects the controls in the toolbox are resolved via the installed in the project NuGet package. Additionally, Visual Studio also checks for a NuGet fallback folder and it tries to load the toolbox from there.
I guess you are not having a Telerik UI for WinForms NuGet installed in the project and Visual Studio has tried to load the controls from the fallback folder which is located inside the installation folder of the controls, usually here: C:\Program Files (x86)\Progress\ToolboxNuGetPackages. This feature in Visual Studio is not yet working entirely correctly and that's why you see the controls disabled.
You can resolve the issue by manually installing a Telerik UI for WinForms NuGet inside your project. Please refer to the following article: NET Core Toolbox Version | Telerik UI for WinForms. With an installed NuGet and a fallback folder, Visual Studio will double load the controls, and you will see a similar screenshot:
In order to remove the duplicated controls, the ones without the icons, you will need to remove the fallback NuGet folder. Please open the C:\Program Files (x86)\NuGet\Config folder and delete the Telerik UI for WinForms.config.
As for the feedback item, we will need it to decline it because the issue is inside Visual Studio.
