    1. By comparing the difference in the accessibility trees of the UI, you should judge whether the task is complete given the task instruction.
    2. If you cannot judge based on the observations, you can evalaute it by writing and running a python script to do a further examination. For example, you can use the 'subprocess' module to run the external command in a terminal to check whether an application has been installed.
    You can also call the file system API to do the file check, etc. You can also try to interactive with the environment via other methods or interface you are familiared with.

    **IMPORTANT**
    1. If no python script is needed, you should provide your analysis and put the judgment at the end of the response in this format: Judgment: Yes/No
