Licensing Issue

[Luke]

Good Evening All,

I have recently secured a new Teleik Developer License, and I have updated the controls to the latest version.

When I run my application from within Visual Studio 2022 i am getting an error message displayed across my forms as shown below.

I have clicked on the help button and followed all the steps on the following web link (https://docs.telerik.com/devtools/winforms/licensing/license-key).  I have tried the automatic and the manual installation methods; however, the message is still showing.  I have confirmed that the telerik-license.txt file has been downloaded as well.

Can you please assist with this so I can get the message removed?  

Thank you in advanced.

Hello, Luke,

It seems you already downloaded the license key and it is downloaded in telerik-license.txt file, but can you confirm that this telerik-license.txt file is located in your AppData\Roaming\Telerik directory on your machine. 

Also, you should install the Telerik.Licensing NuGet package from nuget.org. It will add the Telerik.Licensing.Runtime assembly in your project, which is required to activate the WinForms controls. Can you confirm you downloaded the nuget as well? In case you have more that one projects in the solution, note that you need to install the licensing nuget to your top-level project as well. 

When you build the project, the Telerik.Licensing NuGet package automatically locates the license file and uses it to activate the WinForms controls.

The exact steps to obtain a license are described here (steps 1 and 2): Activating the Telerik UI for WinForms Components

Can you follow these steps and let me know whether the watermark disappears on your side?
