# Diagnostic Options for Telerik Licensing ## Environment | Version | Product | Author | | ---------- | --------------------------- | ------------------------------------------------------------------------------- | | 2025.1.205 | Telerik Document Processing | [Desislava Yordanova](https://www.telerik.com/blogs/author/desislava-yordanova) | ## Description This article describes follow-up steps you can take if the **trial** message persists, even after following the steps listed in the [Setting Up Your Telerik Document Processing Libraries License Key](https://www.telerik.com/document-processing-libraries/documentation/distribution-and-licensing/license-key/setting-up-license-key) article. 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 persists. Verify your license details on the [Telerik Purchase](https://www.telerik.com/purchase.aspx?filter=web) page. [Telerik Document Processing](https://www.telerik.com/document-processing-libraries/documentation/introduction) is distributed with several bundles. Learn [What Versions of Document Processing Libraries are Distributed with the Telerik Products](https://www.telerik.com/document-processing-libraries/documentation/knowledge-base/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](https://www.telerik.com/document-processing-libraries/documentation/distribution-and-licensing/license-key/setting-up-license-key). * Use the `TelerikLicensingVerbosity` configuration in your project file to enable detailed licensing diagnostics during build. The following example shows a sample configuration of the project file: ```xml Exe net9.0 MyProjNamespace enable enable diagnostic ``` * Build the project and verify the Output window for confirmation that the license setup is valid. ### Verbosity Values `TelerikLicensingVerbosity` controls how much information the Telerik licensing targets emit during the build process. The available values are: | Mode | Accepted values | Description | | ---------------- | ---------------------------------------------------------------------------------- | ------------------------------------------------------------------------ | | Quiet | `q`, `Q`, `quiet`, `Quiet` | Reduces routine licensing output; high-priority messages remain visible. | | Verbose | `v`, `V`, `verbose`, `Verbose` | Shows more licensing details by increasing message importance. | | Diagnostic | `d`, `D`, `diag`, `Diag`, `diagnostic`, `Diagnostic`, `diagnostics`, `Diagnostics` | Promotes all licensing messages to high importance for troubleshooting. | | Normal (default) | Unset or any unrecognized value | Uses standard licensing output. | For maximum logging during troubleshooting: ```xml diagnostic ``` The following sample build output shows license lookup and resolution messages during a successful rebuild.

Done (00:00:00.3798748) for net10.0-windows ========== Rebuild All: 1 succeeded, 0 failed, 0 skipped ========== ========== Rebuild completed at 12:28 PM and took 22.470 seconds ========== ``` The following sections explain the sample build output above. License locations, entitlements, expiration dates, and resolution results can differ in your environment. ### License Discovery During the **Provision Licensing** phase, the build searches for a Telerik license key in supported locations, including environment variables, project folders, parent directories, and the Telerik user profile directory. After checking multiple locations, a valid license file is found at: C:\Users\MyUserName\AppData\Roaming\Telerik\telerik-license.txt. This confirms that licensing is configured through the standard Telerik user-profile location rather than through environment variables or a repository-local license file. ### License Information The discovered license contains several Telerik and Kendo UI product entitlements associated with the licensed user account. Most subscriptions are active through 18-Aug-2027, including Telerik UI for WinForms (RCWF) and related product suites. The presence of multiple product entitlements indicates a bundled subscription such as DevCraft or a similar Telerik subscription package. ### License Resolution The License Resolution phase validates that the license covers the specific Telerik assemblies referenced by the project. The build confirms valid licensing for: * Telerik UI for WinForms (RCWF) version 2026.3.1007.90 * Telerik Document Processing Libraries (DPL) version 2026.3.1006.100 Both products are covered by an active subscription valid until 18-Aug-2027, allowing the build to proceed without trial limitations or licensing warnings.
