Hi All, I have installed Python 3.6.4 32 bit version in my machine and when executing a python script I am getting an error in Load Python Script Activity. Error:- Load Python Script: There was no endpoint listening at net.pipe://localhost/UiPath.Service/Host\_IPythonService\_5660 that could accept the message. This is often caused by an incorrect address or SOAP action. See InnerException, if present, for more details. ---

I have posted some troubleshooting tips here: > [@Unable to load Python (anaconda) script](https://forum.uipath.com/t/unable-to-load-python-anaconda-script/184453): > > Dear all, I’m trying to load in a Python3.6.8 script made in an Anaconda env. But i get 2 error messages. Most of the time it reads: No endpoint listening at UiPath.Service/Host\_IPythonService\_\*\*\*\* (System.servicemodel.endpointnotfoundexception) or simply could not load python script. Even the simplest of script doesnt work. Any of you got some tips? Many thanks in advance. Greetings ---

Hi @Karan28 , Try installing Python 3.6.4 64 bit version. Even i was facing the same but after installing 64 bit , its working fine for me. Also, Change the environment variable to where your Python executable file is present. Note: You can download Python 3.6.4 version (64 bit) from the below mentioned link. (Under Files) > **[Python Release Python 3.6.4](https://www.python.org/downloads/release/python-364/)** > > The official home of the Python Programming Language Thanks, Hope it helps. Cheers!

@rahulraj987 Yes, Rahul. If you still face that error then change Target to x64 and version as Python\_36 for (3.6 version of Python installed- in UIpath acitivity) in 64 bit of your system. Hope it helps. Cheers! Nitesh ---

@rahulraj987 Please check the Python version and the folder path in which you have downloaded Python file. Also if you can share the screenshot,it would help understanding error more.(Also the Python scope which you are trying)
