A valid Telerik Reporting license is available, but the Telerik Document Processing Libraries is not explicitly used in the project. + +Possible warning messages: + +`Telerik and Kendo UI Licensing warning TKL101: Telerik Document Processing Libraries is not listed in your current license file.` + +`Telerik and Kendo UI Licensing warning TKL102: Your current license has expired and is not valid for Telerik Document Processing Libraries version 2025.2.807.20.` + +## Solution + +This unexpected behavior was introduced with the 2025 Q3 release due to newly added DPL code that is being used internally. + +The possible solution is to ignore the warning. If the project treats warnings as errors, add an exception to the rule in the csproj file. + +Follow the steps: + +1. Ignore the warning if you are not explicitly using Telerik Document Processing Libraries outside of the Report Viewer. +1. If your project treats warnings as errors, add an exception to the rule in the `.csproj` file. Use the following configuration: + +````XML + + true + TKL102;TKL004 + +```` + +>note This configuration suppresses the specific warnings `TKL102` and `TKL004` related to the Telerik Document Processing Libraries license not being found. +
