    Hi Praveen,

    When I tried to use "Launch Macro Window", I am getting the following issue: 

    Also where can we get the information regarding the registers shown in the AFEGUI?

    Hi Aswath,

    This issue occurs when the required version of Python might not be installed. 

    Notifier timeout error 5000 occurs

    1. User might have installed 32bit Python v2.7 over 64bit Python v2.7.
    2. How the GUI works is that it checks for the system registry for 32bit Python v2.7 on initialization and uses this information to invoke the Python script upon calling(Clicking "Launch Script" Button in GUI.
    3. The system registry will not get updated when 32bit Python is installed over 64bit Python hence preventing the GUI from launching Python macro.

    Please try the below methods and try relaunching the Python Macro

    1. Install 32bit  Python v2.7
    2. Restart the GUI
    3. Completely uninstall the 32bit Python v2.7 and 64bit Python v2.7 and reinstall 32bit Python v2.7. (64bit Python v2.7 could still be installed in the PC in a different directory not C:\Python27)

    For the registers information, refer to the datasheet.

    Hi Praveen,

     I have checked the type of python27 I have in my system. Its 64bit. 

    Checked for 32 bit version and the system doesn't have one. Also, specifically I want to capture the ppg data via python without the usage of AFE44X0GUI. A serial communication between python script and the AFE eval kit.

    Hi Aswath,

    You will need to completely uninstall the 64bit Python v2.7 and reinstall 32bit Python v2.7. To install the 32bit Python v2.7, you could reinstall the GUI.

    I got confused with this statement and installed 64 bit version. Thanks for clarifying. I installed the python2 32bit version and tried `Launch Macro Window` still I am facing the same issue. Checked the registry of the windows machine, python path is present.
