This message is shown when you command TestComplete to update a Test Visualizer frame and TestComplete is unable to capture a new image. In some cases, the message contains additional information on the issue: The window shown in the image was not found: <window name>. This information is shown when TestComplete is unable to recognize the application's windows under test.

The problem typically occurs when your tests work with one browser (for example, with Internet Explorer), but you also have another browser (for example, Google Chrome) launched. TestComplete cannot distinguish them, as a result, an error occurs.

To resolve the problem, close the message box and the browser that is not needed and try to update the Visualizer frame again.

If the message does not contain any additional information, the problem can be caused by any of the following:

The tested application is not running.
The object does not exist in the tested application. For example, the window shown in the Visualizer frame is not open in the application.
The object specified by a mapped name or alias cannot be identified. This can be caused by different reasons, for example:
- Your tested application has changed and the object specified by its mapped name or alias has other identification property values.
- The specified mapped object name or alias was removed from the project’s Name Mapping item.
- The project does not contain the Name Mapping project item (for example, it was removed from the project).

After you close the message box, make sure that your tested application is running, the object is available in the application, the object’s identification criteria are correct in Name Mapping and try to update the Visualizer frame again.
