+## Description
+
+ Despite adding the license key file `TelerikLicense.cs`, the documents displayed the trial version message. Learn how to better diagnose the issues of the trial version message in Telerik products when using a DevCraft UI License.
+
+This knowledge base article also answers the following questions:
+- How to properly set up Telerik Document Processing license keys?
+- How to resolve trial version messages?
+- How to verify included assemblies for Telerik Document Processing?
+
+## Solution
+
+Ensure your license includes the respective product. Without a valid license for the respective Telerik product, the trial version message will persist. Verify your license details on the [Telerik Purchase](https://www.telerik.com/purchase.aspx?filter=web) page.
+
+Telerik Document Processing is distributed with several bundles. Learn [What Versions of Document Processing Libraries are Distributed with the Telerik Products]({%slug distribute-telerik-document-processing-libraries-net-versions%}). To integrate and validate its license, follow these steps:
+
+* Remove any environment variables such as `KENDO_UI_LICENSE` or `TELERIK_LICENSE `, as they may cause licensing issues due to length limitations on Windows. Instead, use the `telerik-license.txt` file as described in [Setting Up Your Telerik Document Processing Libraries License Key]({%slug setting-up-license-key%}).
+
+* Use the `TelerikLicensingVerbosity` configuration in your project file to enable detailed licensing diagnostics during build. A sample configuration of the proj file is shown below:
+
+   ```xml
+   <Project Sdk="Microsoft.NET.Sdk">
+     <PropertyGroup>
+       <OutputType>Exe</OutputType>
+       <TargetFramework>net9.0</TargetFramework>
+       <RootNamespace>MyProjNamespace</RootNamespace>
+       <ImplicitUsings>enable</ImplicitUsings>
+       <Nullable>enable</Nullable>
+       <TelerikLicensingVerbosity>diagnostic</TelerikLicensingVerbosity>
+     </PropertyGroup>
+     <ItemGroup>
+       <PackageReference Include="Telerik.Documents.Spreadsheet" Version="2025.2.520" />
+       <PackageReference Include="Telerik.UI.for.AspNet.Core" Version="2025.1.227" />
+     </ItemGroup>
+   </Project>
+   ```
+
+* Build the project and verify the Output window for confirmation that the license setup is valid.
