You can use the ![](invantive-control-debug-button.png) “Show Trace” function to analyse any errors in the operations of Invantive Control for Excel. The window is only displayed if the “Show Trace” button is enabled; see [Model Developer User Interface](invantive-control-user-interface-model-developer). Invantive Support may ask you to enable “Show Trace” and send them the logs to help analyse any issues. ![](invantive-control-error-trace-analysis-window.png)
